The WME08/HP40C heat pump consumer unit brings a 40A Type B HP RCD, surge protection, main switch and 16A MCB protection together in a metal enclosure. It gives installers a dedicated board configuration to specify for a heat-pump project, with the protective devices and enclosure supplied together.

Choose this version when the heat-pump manufacturer's requirements and your circuit design call for Type B HP residual current protection with MCB-protected outgoing circuits. If your schedule needs two additional RCBOs, compare the WME08/HPR40C version below.

What this heat-pump board gives you

  • Type B HP protection: the fitted WHP RCD is designed for smooth DC and higher-frequency residual currents associated with inverter-driven equipment.
  • Separate protection functions: the 40A rating belongs to the RCD; the listed outgoing MCB rating is 16A. This is not a board supplied with a 40A outgoing MCB.
  • Integrated Type 2 surge protection: an SPD is included in the assembly to address transient overvoltages.
  • A compact metal enclosure: 232mm wide × 240mm high × 112mm deep, helping you check the available mounting space before ordering.

Match the supplied breakers to your circuit schedule

Whitecliffe lists 16A C-curve MCBs for WME08/HP40C. The gallery shows an example assembly with mixed B16/C16 markings, so confirm the quantity and trip curve of each supplied MCB before ordering. The manufacturer's 8-module description identifies the enclosure variant; it does not mean eight spare outgoing ways remain after the equipment is fitted.

Get the right board for the job

contact Power & Data UK quoting WME08/HP40C, your heat-pump make and model, the required breaker schedule, quantity and delivery date. We can check the listed configuration and availability against your requirements before you commit to the order. If the product is shown as unavailable, ask for the current lead time.

Type B HP protection should be selected from the equipment instructions and installation design; it is not a universal requirement for every heat pump. Need just the RCD for a specified compatible assembly? See the WHP240-030 Type B HP RCD.
