Type 2 DIN Rail Surge Protector for Distribution Boards and OEM Panels
LEEYEE supplies Type 2 DIN rail surge protectors for low-voltage AC distribution boards, sub-panels, industrial control cabinets and OEM electrical assemblies. This page helps buyers choose a panel-level SPD by voltage, poles, discharge current, installation point and project need.
What is a Type 2 DIN rail surge protector?
A Type 2 DIN rail surge protector is a panel-mounted surge protective device used to limit transient overvoltage in low-voltage electrical distribution systems. It is commonly installed inside distribution boards, sub-panels, industrial cabinets and OEM electrical assemblies to help protect downstream electrical equipment.
How to choose a Type 2 DIN rail SPD
A good Type 2 SPD selection starts with the electrical system, not only the kA value. Use the table below as a practical first check before requesting a quotation.
| Selection Point | What to Check | Why It Matters | Buyer Note |
|---|---|---|---|
| System voltage | Uc / maximum continuous operating voltage | The SPD voltage rating must match the actual AC system. | Do not choose only by nominal voltage name. |
| System wiring | Single-phase, three-phase, TN, TT or other system type | The pole configuration must match the panel wiring. | Confirm 1P, 2P, 3P, 4P or N-PE design. |
| Discharge capacity | In and Imax values | These values help define the SPD surge current handling capability. | Compare products by full datasheet, not only one kA number. |
| Schutzniveau | Up value | Lower voltage protection level can help reduce stress on downstream equipment. | Check the protected equipment sensitivity. |
| Installation position | Main board, sub-board, control cabinet or OEM panel | Installation point affects the suitable SPD type and coordination. | Use Type 1+2 when the incoming side has higher lightning exposure. |
| Backup protection | Fuse or breaker coordination | Backup protection must follow the SPD datasheet and panel design. | Ask for datasheet before final panel assembly. |
Where Type 2 DIN rail SPDs are commonly used
Type 2 DIN rail SPDs are especially useful where the buyer needs modular, panel-level protection inside standard electrical enclosures.
Main and sub-distribution panels
Used to protect downstream AC circuits in commercial, residential, industrial and utility-related low-voltage distribution systems.
Industrial control and automation panels
Suitable for cabinets with power supplies, PLCs, meters, controllers, drives and other sensitive electrical devices.
Panel builders and equipment manufacturers
Useful for OEM electrical assemblies where the SPD must fit a repeatable DIN rail layout and project supply chain.

Installation details to confirm before ordering
Type 2 DIN rail SPDs should be selected and installed according to the actual panel design, local electrical requirements and the manufacturer datasheet.
Check before selection
- System voltage and maximum continuous operating voltage.
- Single-phase or three-phase wiring.
- Earthing system and pole configuration.
- Required In, Imax and Up values.
- Available DIN rail space inside the cabinet.
- Backup fuse or circuit breaker requirements.
Avoid these mistakes
- Choosing only by the highest kA number.
- Ignoring the real panel wiring system.
- Using a Type 2 SPD where Type 1+2 is required.
- Installing with long and messy connection leads.
- Skipping backup protection coordination.
- Replacing models without checking datasheets.

Type 2 DIN rail surge protector FAQs
What is a Type 2 DIN rail surge protector used for?
It is used for panel-level surge protection in low-voltage electrical distribution systems, including distribution boards, sub-panels, control cabinets and OEM electrical assemblies.
Is Type 2 SPD enough for all panels?
Not always. Type 2 is commonly used for distribution-level protection. If the installation is at the incoming side with higher lightning exposure, a Type 1+2 SPD may be required depending on the project design.
Can a Type 2 AC SPD be used for solar DC circuits?
No. AC and DC SPDs are not interchangeable. Solar PV DC circuits require DC-rated SPDs with suitable Ucpv, polarity and DC disconnection design.
What information should I send before requesting a quote?
Please send system voltage, AC wiring type, pole configuration, installation location, required standard, quantity, target market and any datasheet or panel drawing if available.
Does LEEYEE support OEM Type 2 DIN rail surge protectors?
Yes. LEEYEE supports OEM projects for Type 2 DIN rail SPDs, including model selection, label, packaging and B2B supply communication.
