Part No Description
WHP240-030 40A Type B HP RCD for Heat Pumps & Inverters
The WHP B Type RCD is designed to detect and trip under smooth DC faults at any level. Tested to operate at frequencies above 20 kHz, with a minimum tripping threshold of 150 mA for frequencies over 1 kHz.
Type B High-Performance RCDs: Technical Overview
• Two pole two module: Space saving design enables easier installation using standard busbar.
• Compliance with BS 7671 Standards: These devices meet the requirements set out in BS 7671, ensuring they provide the necessary protection in modern electrical installations.
• Effective Operation at High Frequencies: Designed to function reliably at frequencies of 20 kHz and above, making them suitable for applications involving variable-speed drives and heat pump systems.
• Detection of Smooth DC Fault Currents: Capable of detecting and interrupting continuous smooth DC residual currents, which is essential for comprehensive fault protection in systems where such currents may be present.
Dimensions (WxHxD): 36 x 82 x 70mm
