The WME08/HPR40C 8 Way Heat Pump Consumer Unit is a dedicated heat pump protection board for inverter-driven systems. It is supplied in a compact metal enclosure with a Type B HP RCD, Type 2 surge protection, 1 x 16A C Curve MCB and 2 x 16A RCBOs.
It is a strong fit for renewable installations where the heat pump circuit needs the correct high-frequency DC fault protection associated with Type B HP devices, while also allowing for extra outgoing circuit protection within the same board. Supplied pre-configured, it helps reduce assembly time and keeps the install neat, consistent, and ready for site wiring by a qualified electrician.
Installer Note: This variant is designed for heat pump applications where smooth DC residual currents and higher-frequency fault conditions may be present. The fitted Type B HP RCD is intended for these inverter-driven environments.
Why choose this 8 way heat pump board?
The WME08/HPR40C is the 8 way heat pump board variant with additional RCBO protection built in. Compared with the standard HP40C board, it gives installers a more flexible factory-built layout while staying in the same compact 232 x 240 x 112mm enclosure.
Key features
- Purpose-built heat pump board: designed for inverter-driven heat pump installations
- Factory-fitted protection: 40A Type B HP RCD, 1 x 16A C-curve MCB, 2 x 16A RCBOs, and Type 2 SPD
- Compact enclosure: 232 x 240 x 112mm metal 8-module format
- Cleaner installation: pre-configured board reduces on-site assembly time
- Part of the Whitecliffe heat pump board range: available in alternative configurations and sizes
Type B HP RCD protection for inverter-driven heat pumps
Whitecliffe’s heat pump board range is built around Type B HP RCD protection for modern inverter-driven systems. These devices are designed to detect smooth DC residual currents and operate at higher frequencies associated with heat pump equipment.
This matters because some standard RCD types may not be suitable for heat pump applications where smooth DC or high-frequency residual currents can be present. The manufacturer’s heat pump RCD guidance specifically positions the Type B HP device for this use case.
Heat pump board variants
| Variant | Configuration | Best For |
|---|---|---|
| WME08/HP40C | 8-way board with Type B HP RCD, 16A C-curve MCBs and Type 2 SPD | Standard dedicated heat pump protection in a compact 8-way format |
| WME08/HPR40C | 8-way board with 40A Type B HP RCD, 1 x 16A C-curve MCB, 2 x 16A RCBOs and Type 2 SPD | Installations needing extra outgoing circuit protection within the same compact enclosure |
