40A Type B HP Heat Pump RCBO
The 40A Type B HP Heat Pump RCBO from WCED provides specialist protection for higher-rated modern heat pump circuits. The WHR140B-030 combines a 40A B Curve overcurrent characteristic with 30mA Type B HP residual-current protection, helping protect inverter-driven equipment against a broad range of residual fault conditions.
Designed specifically for heat pump applications, the WHR140B-030 detects smooth DC residual currents and operates effectively in high-frequency environments above 20kHz. Its 10kA breaking capacity and compact 1P+N arrangement make it a powerful option for contemporary residential and commercial heat pump installations.
High-Performance Type B HP RCBO
Modern heat pumps can generate high-frequency leakage currents as part of the AC-to-DC conversion used by inverter-driven compressors. The WHR140B-030 is engineered for these conditions while retaining reliable smooth DC fault detection and 30mA residual-current protection.

Specialist Protection Without Automatically Adding Another Enclosure
The WHR140B-030 brings specialist Type B HP functionality into a single 18mm module. In a suitable consumer unit with the required spare way, capacity and compatible arrangement, it can be fitted alongside other devices, potentially avoiding the need for a separate heat pump board solely to house the protective device.
For installers, this provides greater flexibility when designing new systems or upgrading an existing WCED distribution arrangement, while the final circuit design remains subject to the requirements of the particular installation.
