Description Reviews FAQSs Technical Specs Installation Notes

The WRB125B-030 High Immunity Type A Mini RCBO is a 25A B Curve protective device that combines overload, short-circuit, and residual current protection in a single compact unit. At just 18mm wide, it’s ideal for space-limited boards in residential or light commercial installs. With 30mA Type A sensitivity and high immunity against nuisance tripping, it ensures safe operation on socket, appliance, and lighting circuits in line with 18th Edition standards.

Installer Tip: Use the 25A B Curve for small power circuits and appliances where a 25A rating is required. For inrush-heavy circuits, choose the 25A C Curve variant.

Key Features

  • 25A rated current – protects medium-load circuits
  • B Curve tripping – suited for standard residential and light commercial use
  • Type A sensitivity – detects AC + pulsating DC leakage
  • High immunity design – reduces false tripping
  • Compact 18mm width – ideal for retrofit and consumer unit upgrades
  • Switched live & neutral – full circuit isolation
  • Bi-directional – suitable for PV and EV systems
