The WHA12-PME is a heavy-duty IP65-rated plastic enclosure with 12 usable DIN ways, designed for larger outdoor electrical installations where reliability and protection are essential. Built for EV charger clusters, workshops, heat pump supplies, and garden distribution circuits, it provides ample space for multiple breakers, RCDs, and surge devices.
Each enclosure includes Earth and Neutral bars for straightforward wiring, with a robust plastic housing that maintains ingress protection against moisture, dust, and impact. The deep body allows comfortable wiring clearance and accessory mounting while keeping the footprint compact for wall installations.
Installer Tip: Use this 12-way version for multi-circuit setups — ideal when combining RCBOs, SPDs, and isolators within one enclosure. Always verify clearances if using 2-pole or 4-pole devices.
