Type B HP
2 mod RCD
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 HP 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.
Type ‘B’ devices are also suitable for type ‘AC’, type ‘A’ and type ‘F’ applications
