The WME12/HP40C 12 Way Heat Pump Consumer Unit is a dedicated protection board for inverter-driven heat pump systems. It is supplied in a 304 x 240 x 112mm metal enclosure with Type B HP RCD protection, Type 2 surge protection, a 16A MCB and 2 x 16A RCBOs.
Installer Note: This 12 way model gives more enclosure space than the 8 way variants while keeping the heat pump-specific Type B HP RCD and Type 2 SPD protection in one pre-wired board.
The WME12/HP40C offers the same pre-fitted protection devices as the 8-way but with extra DIN space. This makes it ideal for larger domestic or light commercial projects, or where spare capacity is required for future circuits. For compact installs, see the 8-way version.
