Surge Protection Device Kit WSPDT2-CB

The WSPDT2-CB SPD Kit is a compact Type 2, 40kA surge protection device designed to guard electrical systems and sensitive equipment against voltage spikes caused by lightning strikes or switching surges. Its slim 1-module, 2-pole design makes it ideal for consumer units where space is at a premium.

This SPD can be wired directly to the main switch without requiring a separate MCB, saving both space and installation time. The kit includes pre-cut cable links for faster fitting, making it a practical choice for electricians working in residential, commercial, and light industrial environments.
