Type 'A' Residual Current Circuit Breakers with overload
Our RCBOs have been designed to combine earth leakage and overload protection in one compact unit. All have a sensitivity setting of 30mA and are available in various current ratings.
These protection devices are suitable for domestic, commercial and industrial applications.
These Type 'A' RCBOs respond to
both AC and pulsating DC residual currents
They are manufactured to comply with BSEN61009.
The Type 'AC' RCBOs respond to AC residual currents only.
The single module RCBO is an electronic unit rated at 10kA designed specifically for fitting into consumer units (plastic and metal)
and distribution boards to give earth leakage protection to an individual circuit.
The two and four module RCBO’s have flag indicators to show the position of the contacts, they also have terminals capable of accepting 25mm² cable.
The two module RCBOs also have an additional flag which changes from white to blue to indicate residual current trip.

All 2 pole RCBOs are 2 modules wide.  Most 4 pole RCBOs are 4 modules wide. 
*Please note: The 40A 4 pole device is 5 modules wide!!
