The WME4L/32 is a 4 way mini metal enclosure with lid, built for housing up to four DIN-mounted devices such as RCBOs, SPDs, rotary isolators, or contactors. Constructed from durable powder-coated steel, it provides a professional, compact solution for small-scale circuit distribution and protection.
Installer Tip: The 4-way enclosure is a popular choice for EV or renewables installs where a small sub-board is required - for example, combining an isolator, RCBO, and SPD within one compact metal case to keep everything compliant and tidy.
