Structural Features of the Type B HP RCBO

Engineered with a high-frequency immunity profile, this Type B HP RCBO prevents nuisance tripping in complex, rapid-switching power installations.

  • High-Frequency Tolerance: Designed to tolerate switching noise ≥20kHz, utilizing a raised 150mA minimum tripping threshold for frequencies above 1kHz.
  • Ultimate Breaking Capacity: Safely clears conditional short-circuit currents up to 10kA, protecting sensitive hardware from catastrophic damage.
  • Comprehensive Detection: Identifies and isolates sinusoidal AC, pulsating DC, and smooth DC faults effortlessly, eliminating traditional RCD “blinding”.
  • Visual Status Verification: Features a transparent trip status observation port alongside a standard green/red contact position indicator.

Field Applications for the Type B HP RCBO

Deploying the EKL17-40BHP model ensures rigorous electrical safety across commercial architectures generating high-frequency direct current leakages.

  • Heat Pump Installations: Optimizes inverter compressor lines, serving as a fully recognized, robust BS 7671-compliant alternative to “B+” RCDs.
  • EV Charging Stations: Detects smooth DC residual currents generated by electric vehicle chargers, protecting both users and the infrastructure.
  • Photovoltaic (PV) Systems: Isolates composite waveform leakages efficiently in commercial solar inverter grid connections.
  • UPS Systems: Secures uninterruptible power supplies and variable-speed drives against erratic high-frequency electrical faults.
