DIN Rail Surge Protector · AC / DC / Solar PV / OEM Panels

Protection contre les surtensions sur rail DIN pour panneaux électriques et armoires OEM

Q: Un protecteur contre les surtensions sur rail DIN est-il le même qu'un SPD de type 2 ?

Le No. du rail DIN décrit comment l'appareil est monté. Le type 2 décrit la classe SPD. De nombreux SPDs de type 2 sont montés sur rail DIN, mais les SPDs sur rail DIN peuvent également inclure des options de type 1, type 1+2 et DC.

Q: Où un protecteur de surtension sur rail DIN est-il installé ?

Il est généralement installé à l'intérieur d'un tableau de distribution, d'un panneau de contrôle, d'une boîte de combinaison, d'un cabinet d'alimentation de télécommunications ou d'un boîtier électrique OEM.

Q: Puis-je utiliser le même SPD sur rail DIN pour les circuits AC et DC ?

Non. Les protecteurs de surtension AC et DC ne sont pas interchangeables. Les systèmes solaires photovoltaïques et autres systèmes DC nécessitent des dispositifs de protection contre les surtensions (SPD) de type DC avec une tension appropriée et un design de déconnexion adéquat.

Q: Quel SPD de rail DIN est le meilleur pour un tableau de distribution ?

Pour la plupart des tableaux de distribution basse tension, un parafoudre de rail DIN de type 2 est le choix courant. Pour les panneaux d'entrée avec une exposition plus élevée aux éclairs, un type 1+2 peut être requis.

Q: Quelles informations devrais-je fournir avant de demander un devis ?

Veuillez fournir la tension du système, le type AC ou DC, le câblage monophasé ou triphasé, le lieu d'installation, la classe SPD si connue, la certification requise, la quantité et le marché cible.

What is a DIN rail surge protector?

A DIN rail surge protector is a surge protective device designed to be mounted on a standard DIN rail inside an electrical panel or cabinet. It helps limit transient overvoltage and discharge surge current, reducing the risk of damage to downstream equipment such as inverters, power supplies, PLCs, meters, communication devices and control electronics.

DIN rail is a mounting method, not a separate SPD class. A DIN rail SPD can be Type 1, Type 2, Type 1+2, AC SPD or DC SPD.

It is mainly used inside electrical panels. Common locations include main distribution boards, sub-panels, combiner boxes and control cabinets.

It must match the actual electrical system. Voltage, AC/DC type, poles, earthing system, discharge current and backup protection should be checked before selection.

Guide d'application

Where DIN rail surge protectors are used

DIN rail SPDs are widely used because they can be installed together with breakers, isolators, contactors, terminal blocks and other modular devices inside standard electrical enclosures.

AC Distribution

Distribution boards and sub-panels

Type 2 DIN rail surge protectors are commonly used in low-voltage AC distribution panels to protect downstream circuits and electrical equipment from transient overvoltage.

PV Solaire

PV combiner boxes and inverter inputs

DC DIN rail SPDs are used on the PV side of solar systems, especially near combiner boxes, DC cabinets and inverter inputs where surge risk can affect the system.

Industrial Cabinets

Control panels and OEM equipment

DIN rail SPDs are suitable for industrial control cabinets, machine panels, telecom power cabinets, automation systems and OEM electrical assemblies.

Buyer Decision

AC, DC, Type 2 or Type 1+2: which DIN rail SPD do you need?

DIN rail surge protector is a broad product category. For real purchasing, buyers usually need a more specific page based on voltage, system type and installation point.

Choose AC DIN rail SPD when:

You are protecting a low-voltage AC distribution panel.
The system is single-phase or three-phase AC.
The SPD is installed in a main board, sub-board or OEM cabinet.
You need Type 2 surge protection for panel-level protection.
You need a modular device that fits standard DIN rail layout.

Choose DC DIN rail SPD when:

You are protecting the DC side of a solar PV system.
The installation is near PV strings, combiner boxes or inverter DC inputs.
The system voltage may be 600V, 1000V or 1500V DC.
You need a DC-rated surge protector, not an AC SPD.
You need clear polarity, suitable Ucpv and PV application support.

Notes d'installation

Installation details that affect surge protection performance

A DIN rail SPD is only effective when the model, wiring, earthing and installation position are suitable. Always check the datasheet and local electrical requirements before final installation.

Good installation practice

Install the SPD close to the incoming line or protected circuit.
Keep connecting leads short, straight and properly routed.
Match the SPD voltage rating with the actual AC or DC system voltage.
Select the correct pole configuration for the wiring system.
Use suitable backup protection according to the SPD datasheet.
Ensure reliable connection to PE or the earth bar.

Erreurs courantes à éviter

Utilisation d'un SPD AC sur un circuit solaire DC.
Selecting only by kA value while ignoring Uc, Up and system type.
Installing the SPD far away from the protected circuit with long wiring loops.
Using Type 3 protection without suitable upstream Type 2 protection.
Ignoring earthing system, backup fuse or certification requirements.
Replacing one model with another without checking the datasheet.

FAQ

DIN rail surge protector FAQs

Un protecteur contre les surtensions sur rail DIN est-il le même qu'un SPD de type 2 ?

No. DIN rail describes how the device is mounted. Type 2 describes the SPD class. Many Type 2 SPDs are DIN rail mounted, but DIN rail SPDs can also include Type 1, Type 1+2 and DC options.

Où un protecteur de surtension sur rail DIN est-il installé ?

It is usually installed inside a distribution board, control cabinet, combiner box, telecom power cabinet or OEM electrical enclosure.

Puis-je utiliser le même SPD sur rail DIN pour les circuits AC et DC ?

No. AC and DC surge protectors are not interchangeable. Solar PV and other DC systems require DC-rated SPDs with suitable voltage and disconnection design.

Quel SPD de rail DIN est le meilleur pour un tableau de distribution ?

For most low-voltage distribution boards, a Type 2 DIN rail SPD is the common choice. For incoming panels with higher lightning exposure, Type 1+2 may be required.

Quelles informations devrais-je fournir avant de demander un devis ?

Please provide system voltage, AC or DC type, single-phase or three-phase wiring, installation location, SPD class if known, required certification, quantity and target market.

LEEYE prend-il en charge les protecteurs contre les surtensions sur rail DIN OEM ?

Yes. LEEYEE supports OEM and distributor projects, including product selection, private label, packaging, series supply and B2B project communication.
