Description
The WME18/SP is an 18 module surge protected metal enclosure fitted with a 100A main switch and integrated Type 2 Surge Protection Device (SPD). It’s built for EV-ready installs, domestic distribution boards, and renewable systems where extra capacity is needed for multiple outgoing circuits.
With 15 usable ways, the WME18/SP provides ample space for multi-charger EV hubs, heat pump circuits, or PV inverter connections. The enclosure is made from 1.2mm non-combustible steel with a powder-coated white finish, featuring raised DIN rail, generous wiring room, and multiple knockouts to simplify installation.
Installer Tip: The 18 module board is ideal when a 16 module leaves you short on space. Choose this size if you expect future circuit expansion alongside EV and renewable installs.
