## Summary description

Eti-Polam surge arrester C T2 275/20 (002440393) is a Type 2 SPD designed for protection of electrical installations against transient overvoltages. Specified with a nominal voltage rating of 275 V and discharge/current parameters indicated by “20”, it is suitable for installation in distribution boards to safeguard equipment such as consumer electronics, lighting, and control systems from lightning-induced or switching surges.

## Long description

Eti-Polam C T2 275/20 surge arrester (Type 2 SPD) is designed to protect electrical installations and connected equipment from transient overvoltages caused by lightning strikes or switching events. With a nominal voltage rating of 275 V and discharge characteristics indicated by the “20” designation, this SPD is intended for mounting in distribution boards where it provides a controlled path for surge currents and reduces stress on downstream devices such as consumer electronics, lighting, and control systems.
Advantages
The device offers coordinated protection for low-voltage networks by limiting transient overvoltages and diverting surge currents away from sensitive equipment. Its compact form factor allows installation within standard distribution boards, and the Type 2 classification ensures suitability for common mains protection schemes. The SPD design emphasizes reliable operation under repeated transient conditions and compatibility with downstream circuit breakers and protective devices.
Suitable for
Residential mains distribution boards
Small commercial electrical panels
Protection of consumer electronics, lighting circuits, and control equipment
Supplementary protection in buildings subject to lightning or switching surges
Key specifications
Type: Class/type 2 surge protective device (SPD)
Nominal operating voltage: 275 V (AC mains)
Discharge/current characteristic: indicated by "20" designation for surge handling
Intended mounting: distribution board / electrical panel integration
Application environment: low-voltage AC power systems for residential and light commercial use
How to use
Install the SPD in the distribution board according to local electrical codes and the device manufacturer’s wiring guidelines. Connect the device between the phase and neutral or phase and earth as specified for the particular installation scenario, ensuring secure terminal connections and appropriate conductor sizes. Coordinate the SPD placement with upstream and downstream protective devices (fuses, breakers, RCDs) to maintain selectivity and ensure the SPD can divert surge currents safely to earth.
Usage recommendations
Verify compatibility with the building’s earthing system and follow national wiring regulations. Periodically inspect the SPD for visual signs of operation or damage and replace it if recommended by the manufacturer after significant surge events. When integrating into critical installations, consider combining Type 2 protection with upstream Type 1 or downstream Type 3 devices for layered surge protection.
