Description Reviews FAQSs Technical Specs Installation Notes

The WRB116B-030 High Immunity Type A Mini RCBO is a 16A B Curve device designed to protect small power and lighting circuits while saving space in the board. At just 18mm wide, it combines residual current and overcurrent protection in one compact module. With 30mA Type A sensitivity and high immunity design, it delivers reliable protection against AC and pulsating DC leakage currents in compliance with the 18th Edition regulations.

Installer Tip: Use the 16A B Curve for radial socket circuits, lighting banks, or small fixed appliances. For circuits with motors or higher inrush currents, see the 16A C Curve variant.

Key Features

  • 16A rated current – suitable for small power and lighting circuits
  • B Curve tripping – designed for standard residential and light commercial loads
  • Type A sensitivity – detects AC + pulsating DC leakage
  • High immunity – reduces nuisance tripping under harmonic-rich conditions
  • Single-module width (18mm) – saves space inside the board
  • Switched live & neutral – isolates both conductors
  • Bi-directional – safe for use with PV and EV installs
