Type 'AC' 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.
All the RCBOs respond to AC residual currents
and are manufactured to comply with BSEN61009.
The Type 'A' RCBOs respond to
both AC and pulsating DC residual currents.
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 module RCBO’s, rated at 10kA have flag indicators to show the position
of the contacts, they also have terminals capable of accepting 25mm² cable.
There is also an additional flag which changes from white to blue
to indicate residual current trip.
4 pole devices are available in Type 'A', 'C' curve.
