The WIS2100 2-Pole 100A Main Switch provides safe and reliable isolation for residential, commercial, and light industrial electrical systems. Designed with twin screw terminals for a secure and stable fit, this switch ensures strong connections that reduce the risk of loose wiring or overheating.

Its double-pole design isolates both live and neutral conductors, making it an essential choice for consumer units, submains, and distribution boards. A colour-coded operating handle improves visibility and ease of operation, ensuring quick identification in an emergency or maintenance scenario.

Compact at only 35mm wide, this 100A main switch is ideal where space is limited, while still delivering the high capacity required for modern electrical installations. For pre-fitted options, see our 6 Way Consumer Units or 8 Way Consumer Units.
