FuseBox Type B HP RCD 63A 30mA – RTBHP630302
The FuseBox Type B HP RCD 63A 30mA (RTBHP630302) is a specialist 2-pole residual current device developed for inverter-driven heat pump installations. Designed to detect AC, pulsating DC and smooth DC residual fault currents, this Type B HP RCD provides enhanced protection where high-frequency leakage currents may occur.
Unlike conventional RCDs, the RTBHP630302 is designed for high-frequency operation, with a capability extending beyond 20kHz. It distinguishes normal high-frequency leakage from genuine fault conditions, making it particularly suitable for modern heat pump systems.

Designed for Inverter Heat Pumps
Modern inverter-driven heat pumps can generate high-frequency residual currents during normal operation. These characteristics make the selection of an appropriate RCD particularly important.
The FuseBox Type B HP RCD 63A 30mA is specifically developed for these applications. Its high-frequency capabilities help distinguish normal operational leakage from genuine residual current faults, supporting dependable protection in suitable heat pump installations.
High-Frequency Residual Current Protection
The RTBHP630302 detects AC, pulsating DC and smooth DC residual fault currents. It has been tested at frequencies greater than 20kHz and maintains a 150mA tripping threshold above 1kHz.
These characteristics make the device particularly useful where inverter technology produces residual current components at higher frequencies.
