Noark Ex9M moulded case circuit breakers

The Ex9M moulded case circuit breakers from Noark are now available in Australia. The Ex9M offers protection for circuits and electrical equipment in overload, short-circuit and undervoltage situations. The circuit breaker deviates from traditional linear forms and instead features a gentle arc at the front.

The Ex9M moulded case circuit breaker offers many advantages over traditional design MCCBs; the patented rotating shaft with bearing allows the circuit breaker to have a smaller main spring force tension and offers lower friction and abrasion within the switch mechanism than traditional designs. The patented snap action mechanism offers an accelerated breaking time of within 2 ms, and its breaking and current limiting capacity are improved by utilising a gas-flushing principle.

For ease of installation and space-saving considerations, the volume of the Ex9M series is designed and manufactured to be compact in size and light in weight without compromising performance. The breakers can be mounted in all directions and can be fed from the top or bottom to increase flexibility in panel design.
