16A Type B HP Heat Pump RCBO
The 16A Type B HP Heat Pump RCBO from WCED is designed specifically for modern heat pump circuits where smooth DC and high-frequency residual currents may be present. The WHR116B-030 combines B Curve overcurrent protection with 30mA residual-current protection in a compact single-module 1P+N format.
Modern inverter-driven heat pumps can create electrical conditions that differ significantly from conventional loads. The WHR116B-030 is engineered to detect smooth DC residual currents and operate effectively at frequencies above 20kHz, providing specialist protection for contemporary heat pump installations.
Specialist Type B HP Protection
This 16A Type B HP Heat Pump RCBO is designed to provide reliable operation in environments where high-frequency residual currents may occur. Above 1kHz, the WHR range uses a minimum 150mA tripping threshold, helping it cope with high-frequency leakage while maintaining protection against smooth DC faults.

Heat Pump Protection Without Automatically Requiring a Separate Board
A major advantage of the WHR116B-030 is its space-saving single-module construction. Where the existing consumer unit arrangement, available capacity and installation design permit, this Type B HP RCBO can be installed alongside other compatible protective devices instead of automatically requiring a separate dedicated heat pump consumer unit.
The standard busbar-compatible design can make the WHR116B-030 particularly useful for retrofit heat pump installations where suitable space is already available within the distribution board.
