Description
️Type B HP 40A RCD for Heat Pumps
Bi-Directional Type B HP 40A RCD for Heat Pumps
The ️Type B HP 40A RCD for Heat Pumps is specifically designed for modern heat pump systems, inverter-driven equipment and applications where smooth DC residual currents and high-frequency leakage currents may be present. Unlike standard RCDs limited to lower frequencies, this advanced Type B HP device is verified to operate at frequencies above 20kHz, making it ideal for low-carbon heating and renewable energy installations.
Modern heat pumps with inverter-driven compressors generate high-frequency electrical currents during AC to DC conversion. Standard AC, Type A and even some conventional Type B RCDs may not provide reliable protection under these conditions. The Type B HP 40A RCD for Heat Pumps is engineered specifically for these demanding applications, helping reduce nuisance tripping while maintaining dependable fault protection.
This device detects and trips under smooth DC faults at all levels and provides a minimum tripping threshold of 150mA for frequencies above 1kHz. The compact two-pole, two-module design enables easier installation using standard busbar systems while saving valuable space within consumer units and distribution boards.
The Bi-Directional design also makes this RCD suitable for modern installations where current flow direction may vary, including heat pumps, battery storage systems, inverter applications and renewable energy systems.
