WMCU4 is a 4 way metal enclosure supplied empty for custom circuit builds, add-on protection arrangements, and small distribution applications. It provides a compact steel housing for installers who need to populate the enclosure with their chosen protective devices.

This enclosure is suited to retrofit work, local sub-circuit protection, and specialist builds where a small metal board format is required. Its empty chassis design allows flexibility when configuring MCBs, RCBOs, or other compatible circuit protection devices to suit the installation.
