The WME28/SP is a 28 module surge protected metal enclosure fitted with a 100A main switch and a factory-installed Type 2 Surge Protection Device (SPD). Designed for EV hubs, large domestic boards, and renewable system installs, it delivers safe isolation and full surge compliance in a robust steel housing.
With 24 usable ways, the WME28/SP offers extensive capacity for multi-charger EV bays, heat pump and PV circuits, or combined domestic and commercial loads. Constructed from 1.2mm non-combustible steel with a powder-coated finish, the enclosure features a raised DIN rail, knockouts, and ample wiring space for faster, tidier installs.
