Type B HP Heat Pump RCBO – Single Module

Type B HP heat pump RCBO combining overcurrent and residual-current protection in a single 18mm module. It is intended for inverter-driven heat pump circuits where the equipment manufacturer or circuit design calls for Type B residual-current protection.

• Type B HP residual-current protection for smooth DC and high-frequency residual currents
• 30mA sensitivity for additional protection
• 10kA breaking capacity
• 1P+N with switched live and neutral
• Single-module, 18mm format for DIN rail assemblies
• Bidirectional design
• Manufactured to IEC/BS EN 62423 and IEC/BS EN 61009-1

The WHR range is engineered for operation at frequencies above 20kHz, with the manufacturer stating a minimum tripping threshold of 150mA for frequencies above 1kHz. Selection must follow the heat pump manufacturer’s instructions and the requirements of the installation design.
