Type 2 Surge Protection Kit with Cable – No MCB Required
Niglon NSA2-240 – Compact Pluggable SPD with Neutral & Earth Links
The Niglon NSA2-240 Type 2 Surge Protection Kit is a compact and reliable SPD solution, designed to protect electrical installations from transient overvoltages caused by lightning strikes or switching operations. Compliant with BS EN 61643-11, this Type 2 surge protection device (SPD) is suitable for earthing types TN-C, TN-C-S, IT & TT, ensuring comprehensive protection in commercial and industrial environments.
Unlike traditional surge protection setups, this single-module SPD does not require an MCB breaker, making installation simpler while saving valuable space in the distribution board. This feature allows for a more streamlined and efficient electrical setup, reducing installation time and costs.
Equipped with pluggable modules, this SPD allows for quick and easy replacement in case of failure. It includes built-in neutral and earth links, reducing wiring complexity and enhancing safety. The local indicator provides a clear visual status, with green indicating normal operation and red signalling failure.
