EKL6-100BHP is a Type B HP Residual Current Device(RCD) for heat pumps, available in 1P+N and 3P+N up to 100 A. It detects AC, pulsating DC, and smooth DC, and is specially optimized for high-frequency leakage from inverter compressors. It operates beyond 20 kHz, with a raised 150 mA trip threshold above 1 kHz, reducing nuisance tripping. Tolerance to DC prevents RCD "blinding" and ensures reliable fault detection.
Compliant with BS 7671 for heat pump installs, EKL6-100BHP is a robust, recognized alternative to “B+” RCDs. Its high-frequency and heat pump tuning makes it ideal not only for heat pumps, but also for PV, EV charging, and variable-speed drives.
