Description
The WME12/SP is a 12 module surge protected metal enclosure fitted with a 100A main switch and an integrated Type 2 Surge Protection Device (SPD). Built for EV charger supplies, domestic distribution upgrades, and renewable systems, it provides safe isolation and reliable surge defence in a durable steel housing.
With 9 usable ways, the WME12/SP offers more space than smaller boards, making it ideal for EV installs with multiple outgoing circuits, hybrid heat pump systems, or PV inverter connections. Each enclosure is built from 1.2mm non-combustible steel, powder-coated in white, and designed for fast, tidy installs with raised DIN rail, knockouts, and ample wiring room.
Installer Tip: The 12 module version is a sweet spot for EV or renewable installs that need extra ways beyond a simple charger supply — giving flexibility without the size of larger boards.
