Most people think that their residual current circuit breaker with overload protection (RCBO) trips out because the circuit is either overloaded or incorrectly rated. This is often not the case, as ambient temperature plays a key part in how a normal thermal residual current device (RCD)/RCBO operates.

Most RCD/RCBOs operate on a thermal residual current system which is affected by ambient temperature. This causes the internal mechanism to overheat and then trip out, even though the load isn’t more than the rating. These cause onerous callouts which are not only expensive but also irritating to your customer.

The hydraulic magnetic technology of CBI Electric RCBOs and breakers mean that ambient temperature isn’t a factor. They only measure the true load of the circuit, so if you have to send either a staff electrician or a subcontractor to site, you know there is actually a fault.

This means that when evaluating power outages against KPIs, the data you are analysing is accurate. The pole mounted enclosure can accommodate CBI Electric’s range of SFM breakers and SF1EL RCBOs in configurations to provide flexibility and safety to the power authority and the consumer.

CBI Electric Australia also has a range of weatherproof enclosures in varying materials to allow the isolation of power without crossing the boundary into the consumer’s premises.
