Professional range of Allen Bradley general purpose MCBs accessories from the 1492 series. Accessories include auxiliary contacts, single phase busbars, busbar end caps, protective shrouds, shunt trips and terminal power feeds. All accessories are highly reliable and excellent quality.

This circuit trip from Rockwell Automation’s Allen Bradley range is a type of auxiliary contact that supplements the protection provided by your existing MCB. It mounts directly onto an MCB to minimise the risk of harm to people or equipment caused by electrical faults, such as short-circuits, thermal overloads and ground currents. The 2NC contacts on this unit mean you have additional phases in your circuit. This helps to ensure overload faults don’t make it to your main breaker, minimising the risk of equipment failure.
