25A Type B HP Heat Pump RCBO
The 25A Type B HP Heat Pump RCBO from WCED is engineered for heat pump installations where inverter technology can produce both smooth DC and high-frequency residual currents. The WHR125B-030 delivers combined overcurrent and residual-current protection in one compact 1P+N module.
Rated at 25A with a B Curve characteristic, the WHR125B-030 provides 30mA residual-current sensitivity together with a 10kA breaking capacity. Its Type B HP performance is designed specifically around the electrical behaviour of modern heat pump systems.
Smooth DC and High-Frequency Detection
Unlike basic residual-current protection intended for conventional loads, the WHR125B-030 can detect smooth DC fault currents and is engineered to function at frequencies extending beyond 20kHz. This gives installers a purpose-designed protective device for modern inverter-controlled equipment.

Compact Alternative for Suitable Existing Boards
The single-module construction can help simplify heat pump upgrades. If the existing WCED consumer unit has suitable spare capacity, compatible busbar arrangement and the installation design allows, the WHR125B-030 can sit alongside other protective devices rather than automatically requiring a separate enclosure.
This makes the 25A Type B HP Heat Pump RCBO particularly useful where installers want specialist heat pump protection while keeping the distribution arrangement compact.
