Description Reviews FAQSs Technical Specs Installation Notes

The WRB110B-030 High Immunity Type A Mini RCBO is a compact 10A B Curve protective device designed for domestic and commercial boards where space is limited. At just 18mm wide, it combines residual current and overcurrent protection in one module. With 30mA Type A sensitivity, it detects AC and pulsating DC leakage currents – keeping circuits compliant with 18th Edition regulations, including EV chargers and renewable installs.

Installer Tip: Use the 10A B Curve for socket circuits or small appliance loads. For higher inrush current circuits, compare with the 10A C Curve version.

Key Features

  • 10A rated current – ideal for sockets and small appliance loads
  • B Curve tripping characteristic – designed for general residential use
  • Type A sensitivity – detects AC + pulsating DC leakage
  • High immunity design – reduces nuisance tripping
  • Compact 18mm width – frees up ways in consumer units
  • Switched live & neutral – ensures full circuit isolation
  • Bi-directional – suitable for PV and EV installs
