32A Type B HP Heat Pump RCBO
The 32A Type B HP Heat Pump RCBO from WCED is a high-performance protective device developed for modern heat pump circuits using inverter and variable-speed technology. WHR132B-030 combines 32A B Curve overcurrent protection with 30mA Type B HP residual-current protection in a single-module 1P+N format.
Its specialist design addresses both smooth DC fault currents and the high-frequency residual currents associated with contemporary heat pump electronics. The device is engineered for operation at frequencies above 20kHz while providing a 10kA breaking capacity.
Purpose-Built Protection for Heat Pump Installations
The WHR132B-030 goes beyond standard low-frequency residual-current protection. It can detect smooth DC residual currents and is designed to manage high-frequency leakage characteristics, with a minimum tripping threshold of 150mA for frequencies above 1kHz.

Add Heat Pump Protection Within a Suitable Consumer Unit
The compact 18mm design is particularly valuable when upgrading a distribution board. Where the existing consumer unit has appropriate spare space, capacity and compatible equipment, the WHR132B-030 may be installed alongside existing protective devices instead of automatically needing a separate dedicated heat pump consumer unit.
Standard busbar compatibility helps make this a practical choice for installations where specialist Type B HP protection needs to be added while preserving consumer unit space.
