The WME22/SP is a 22 module surge protected metal enclosure equipped with a 100A main switch and factory-fitted Type 2 Surge Protection Device (SPD). Designed for EV-ready supplies, domestic distribution upgrades, and renewable installs, it delivers safe circuit isolation and 18th Edition Amendment 2 compliant surge protection in a durable steel housing.
With 19 usable ways, the WME22/SP is ideal for larger domestic boards, light commercial EV hubs, and renewable systems where multiple outgoing circuits must be protected. Constructed from 1.2mm non-combustible steel, it features a powder-coated white finish, raised DIN rail, generous wiring room, and multiple knockouts for quick, neat installs.
Installer Tip: The 22 module version is a strong choice when a 16 or 18 module board doesn’t give enough room. Ideal for EV-ready installs with future expansion in mind.
