Description

The WRB132B-030 High Immunity Type A Mini RCBO is a 32A B Curve protective device designed for medium-load circuits in residential and light commercial installs. Its slim 18mm design combines short-circuit, overload, and residual current protection in one unit. With 30mA Type A sensitivity and high immunity, it ensures safe, stable protection on EV chargers, socket circuits, and fixed appliances in compliance with the 18th Edition.

Installer Tip: Choose the 32A B Curve for general-purpose socket or appliance circuits requiring higher current handling. For motor-driven or inrush-heavy loads, use the 32A C Curve variant.

Key Features

  • 32A rated current – protects larger socket or appliance 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 harmonics
  • Compact 18mm module – space saving for retrofit boards
  • Switched live & neutral – ensures full isolation
