The WME08/HP40C 8 Way Heat Pump Consumer Unit is a dedicated protection board for inverter-driven heat pump systems. It is supplied in a compact metal enclosure with Type B HP RCD protection, Type 2 surge protection and 16A C Curve MCBs.
Installer Note: Whitecliffe’s heat pump range uses Type B HP RCD protection for inverter-driven heat pump systems where smooth DC and high-frequency residual currents may be present. Always confirm the final protective device requirements against the heat pump manufacturer’s specification.
Why choose this 8 way heat pump consumer unit?
The WME08/HP40C is the compact 8 way option in the Whitecliffe heat pump consumer unit range. It suits installs where the heat pump circuit needs dedicated Type B HP RCD protection, surge protection and a smaller enclosure footprint. For larger layouts, see the 12 way version.

Type B HP RCD protection for heat pumps
Modern inverter-driven heat pumps can produce smooth DC and high-frequency residual currents. Whitecliffe’s Type B HP RCDs are designed for this type of application, helping provide the right protection where standard RCD types may not be suitable.
This is the main reason the WME08/HP40C is positioned as a dedicated heat pump consumer unit rather than a standard small distribution board.
