WME 36 Module Surge Protected Metal Enclosure – 100A Main Switch + SPD (WME36/SP)

The WME36/SP is the largest model in the WME range — a 36 module surge protected metal enclosure with a 100A main switch and integrated Type 2 Surge Protection Device (SPD). Designed for large EV hubs, renewable-heavy systems, and commercial distribution boards, it delivers safe isolation and full surge compliance in a robust steel housing.

With 32 usable ways, the WME36/SP is built for multi-charger EV installations, commercial premises, or complex renewable setups where maximum circuit capacity is essential. Constructed from 1.2mm non-combustible steel with a white powder-coated finish, it’s designed for installers with raised DIN rail, knockouts, removable gland plate, and a generous wiring area for neat and efficient connections.
