Automatic transfer switch prices vary widely because the term “ATS” covers very different products. This guide focuses specifically on compact DIN-rail automatic transfer switches such as the LEEYEE ATS-63: PC-class dual-power switches for compact backup systems, available in 2P and 4P versions with rated-current options from 6A to 63A.[1]
For distributors, OEM buyers, panel builders and project procurement teams, the useful comparison is not a 63A compact ATS versus a 400A or 1600A industrial transfer system. The useful comparison is like-for-like: the same compact ATS category, pole count, electrical configuration, quantity, OEM scope and quotation basis.

Quick Answer: What Is the Price of a Compact Automatic Transfer Switch?
As a current public B2B reference, LEEYEE's 63A compact DIN-rail ATS listings show the following FOB price tiers on Made-in-China. These are marketplace reference prices, not a permanent quotation. [3][4]
| Compact ATS | Public Quantity Tier | Public Reference FOB Price |
|---|---|---|
| LEEYEE 2P 63A ATS | 50–1,999 pcs | US$15.26 / pc |
| LEEYEE 2P 63A ATS | 2,000+ pcs | US$13.87 / pc |

Public reference checked in September 2026. The final quotation can change with model selection, quantity, OEM requirements, packaging, documentation, Incoterm, shipment conditions and current commercial terms. Always request a current project quotation before placing an order.
For this compact ATS category, compare 2P with 2P, 4P with 4P, and the same electrical and commercial configuration before deciding which quotation is lower.
What Type of ATS Is This Price Guide About?
LEEYEE ATS-63 is a compact DIN-rail automatic transfer switch designed to transfer a load between power source A and power source B. The current product page lists rated-current options of 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A, with 2P and 4P konfigurasi.[1]
| LEEYEE ATS-63 Parameter | Current Product Data | Arti Pembeli |
|---|---|---|
| Arus yang dinilai | 6A–63A options | State the exact current required in the RFQ |
| Poles | 2P / 4P | Do not compare different pole configurations as the same item |
| Tegangan yang dinilai | AC110V / AC220V / AC400V | Confirm the actual system configuration before quotation |
| Frekuensi | 50/60Hz | Match the destination system |
| Kelas | PC | Compare with the same compact transfer-switch category |
| Kategori penggunaan | AC-31B | Check that the load application matches the product category |
| Waktu perpindahan | <50 ms | Compare switching performance on the same basis |
| Pemasangan | rel DIN | Relevant to compact panel and distribution-board integration |
A useful automatic transfer switch price comparison starts by confirming that both suppliers are quoting this same compact product category.
1. Why 2P and 4P ATS Prices Are Different
Pole configuration is one of the clearest price differences within the LEEYEE compact ATS range. A 2P version switches two conductors, while a 4P version switches four.
The current public LEEYEE marketplace listings illustrate this difference directly: the 2P 63A version is listed at US$13.87–15.26 per piece depending on quantity, while the 4P 63A version is listed at US$15.68–17.25 per piece.[3][4]
LEEYEE's ATS selection guide explains that 2P is commonly used in single-phase systems, while 4P is commonly used where a three-phase system requires L1, L2, L3 and Neutral switching. Final selection must still follow the actual wiring design and project requirements.[2]
2. Rated Current Must Be Defined Before Comparing Price
LEEYEE ATS-63 is available from 6A to 63A.[1] A buyer should therefore avoid sending only “ATS price” or “DIN-rail ATS price” as the RFQ.
The supplier needs to know the required current rating, and the current rating must match the actual load calculation. For motors, pumps or other loads with high starting current, the operating characteristics of the load should also be checked before fixing the ATS rating.[2]
3. Voltage and System Configuration Affect What Should Be Quoted
The current ATS-63 product page lists AC110V, AC220V and AC400V configurations with 50/60Hz operation. [1] The RFQ should state the actual system voltage rather than assuming that every ATS with the same current rating uses the same electrical configuration.
For generator or inverter backup systems, also state the normal source, backup source, phase arrangement, neutral wiring and grounding design. Those details determine whether the proposed ATS configuration is suitable.
4. Compact PC-Class ATS Should Be Compared With the Same Product Category
LEEYEE ATS-63 is specified as a PC-class compact automatic transfer switch. [1] That matters because an online search for “automatic transfer switch price” can also return large breaker-based transfer systems, enclosed transfer switches and complete ATS cabinets.
Those products can use different architectures and serve very different current ranges and project requirements. Their prices should not be used as a direct benchmark for a compact DIN-rail ATS.
The first rule of ATS price comparison is simple: compare the same product architecture before comparing the number.
5. Auto / Manual Operation and Transfer Performance Should Match
The LEEYEE compact ATS supports automatic conversion plus manual operation. The product also uses status indication for source and load conditions. [1]
LEEYEE's current ATS-63 technical data lists a transfer switching time of less than 50 ms. [1] This is the switch transfer time itself. It does not mean that a generator can start, stabilize and restore the complete backup system within 50 ms.[2]
6. Do Not Confuse ATS Price With Protection-Device Cost
An ATS transfers the load between sources. It does not replace the complete protection system. LEEYEE's current ATS guide specifically notes that an ATS does not replace breakers, fuses, surge protection, grounding or correct cable sizing.[2]
The ATS-63 technical page lists a rated short-circuit current Iq of 5kA and a recommended RT16-00-63A fuse for the product family.[1] Project protection still needs to be confirmed against the actual installation.
7. Quantity Is a Real Automatic Transfer Switch Price Factor
For this product category, quantity is not a theoretical factor; the current public LEEYEE listings already show different unit-price tiers for different order quantities.
2P 63A Public Price Tier
- 50–1,999 pcs: US$15.26 / pc
- 2,000+ pcs: US$13.87 / pc
4P 63A Public Price Tier
- 48–503 pcs: US$17.25 / pc
- 504+ pcs: US$15.68 / pc
These public tiers demonstrate why a buyer should state the real purchasing quantity when requesting a quote. A sample, a 100-piece order and a repeat container-scale order should not automatically be expected to use the same unit price.[3][4]
8. OEM Scope Can Change the Final Bulk Quote
LEEYEE's current product and supplier information shows customization support for ATS products. [3] For B2B buyers, “OEM” should be broken into specific requirements rather than treated as one generic option.
| OEM Item | What the Buyer Should Specify | Why It Matters to Price |
|---|---|---|
| Lambang | Printing or marking requirement | Artwork and production setup may differ |
| Label produk | Brand, model code and required technical information | Requires label confirmation before production |
| Instruction manual | Language, brand and model scope | Customized documentation adds preparation work |
| Pengemasan | Standard carton or private-label packaging | Printing, MOQ and packing requirements can differ |
| Persetujuan sampel | Standard sample or customized sample | Custom approval can add setup work before mass production |
9. Certification and Documentation Must Match the Destination Market
LEEYEE's current ATS technical guide states that CE and RoHS documentation can be supplied for the compact ATS range.[2] Buyers should still confirm the exact model, destination country and document scope before ordering.
For projects that reference IEC transfer-switch requirements, the current international standard is IEC 60947-6-1:2026.[5] Do not assume that a product marking, catalogue statement or certificate for one model automatically applies to every configuration. Request the exact documentation required for project approval.
10. FOB Product Price Is Not the Same as Landed Cost
The public price examples above are reference FOB prices from a B2B marketplace. A purchasing team should not compare them directly with a supplier quote using EXW, CIF, DDP or another Incoterm.
Freight, carton quantity, shipment method, customs, local tax and destination charges can change the final landed cost even when the ATS unit price is similar.
How to Compare Two Compact ATS Quotations Fairly
For a compact 6A–63A DIN-rail ATS, you do not need a thirty-field industrial transfer-switch worksheet. A shorter, product-specific comparison is more useful.
| Periksa | Supplier A | Supplier B |
|---|---|---|
| Kategori produk | Compact DIN-rail ATS | Must match |
| Arus yang dinilai | e.g. 63A | Must match |
| Poles | 2P atau 4P | Must match |
| Voltage / frequency | Project configuration | Must match |
| Class / usage category | PC / AC-31B for ATS-63 | Confirm equivalent scope |
| Transfer function | Automatic + manual | Confirm function |
| Protection scope | ATS only or ATS + accessories | Must use same boundary |
| Cakupan OEM | Standard or customized | Must match |
| Kuantitas | Same order quantity | Must match |
| Incoterm | FOB / EXW / CIF / DDP | Use the same basis |
Only compare the final unit price after these conditions are aligned.
What Should a Bulk Buyer Send Before Asking for ATS Pricing?
A useful RFQ for this compact ATS category should include:
Need a Current Price for LEEYEE ATS-63?
Send your current rating, 2P or 4P requirement, voltage, quantity, destination market and OEM requirements. LEEYEE can confirm the suitable ATS-63 configuration and provide a current B2B quotation based on the actual purchasing scope.
Pertanyaan yang Sering Diajukan
How much does a 63A automatic transfer switch cost?
LEEYEE's current public B2B listings show the 2P 63A compact ATS at US$13.87–15.26 per piece and the 4P 63A version at US$15.68–17.25 per piece, depending on quantity. These are public marketplace reference FOB prices rather than permanent project quotations. [3][4]
Why is a 4P ATS more expensive than a 2P ATS?
The 4P version switches four conductors rather than two and uses a different product configuration. Current public LEEYEE listings also show a higher reference price for the 4P 63A version. The correct pole number should still be selected by the electrical system, not by price alone.
Is every 63A ATS directly comparable?
No. Confirm pole count, voltage, transfer architecture, usage category, switching function, protection boundary, installation format and commercial terms before comparing two 63A quotations.
What current ratings are available for LEEYEE ATS-63?
The current product page lists 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A options. [1]
Can the ATS-63 be used for generator or inverter backup?
Yes, when the source voltage, frequency, current, pole configuration, wiring method and application match the ATS operating conditions. The LEEYEE product range is intended for compact backup switching applications including generator and inverter systems.[1]
Does ATS-63 replace a circuit breaker or fuse?
No. The ATS performs source transfer and does not replace the system's required overload, short-circuit and surge protection. Suitable breakers, fuses, SPD, grounding and cable sizing must be selected separately for the project.[2]
Does bulk quantity affect compact ATS price?
Yes. The current public LEEYEE marketplace listings show lower unit-price tiers at higher quantities for both the 2P and 4P 63A versions.[3][4]
What should I send to get an accurate ATS quotation?
Send rated current, pole number, voltage, frequency, normal and backup source, wiring requirements, quantity, destination, OEM needs and required documentation. This is enough to make a compact ATS quotation much more comparable.
