CBI RCBO’s

RCBOs are a combination of a residual current device and miniature circuit breaker, i.e. it protects against earth and over currents.

We offer a range of RCBOs where the functionality of hydraulic magnetic circuit breakers are combined with electronics sensing of earth leakage current.

It´s more and more common to design your installation with individual earth leakage detection in each circuit with RCBOs instead of having one main earth leakage device and separate MCBs. This is a way of eliminating the risk that you have total black out if one earth leakage occurs. With RCBOs in each circuit, only the affected circuit is switched off.

QF17A 5-63A RCBO with 30-300mA sensitivity

QF17A is a very compact RCBO for rated current between 5 and 63A. Standard sensitivity is 30mA but more options are available. The circuit breaker part in QF17A is designed with the same Hydraulic-Magnetic principle as the other CBI MCBs. This means that high or low ambient temperatures is no problem for reliable function. This is then combined with a very exact electronic sensing of earth leakage currents. All together making an excellent product for demanding applications.
