CBI RCBO’s

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

 

We offer a range of RCBOs where the functionality of hydraulic magnetic circuit breakers are combined with electronic 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.
