Industrial automation customers can improve their short-circuit protection with a line of current-limiting, moulded-case circuit breakers from Rockwell Automation. The line expands the Allen-Bradley Bulletin 140G moulded-case circuit breakers and offers more comprehensive, fast-acting, short-circuit protection.
The line expansion protects against overload, short-circuit and ground-fault conditions; is listed as current limiting; and reacts to circuit overloads two to three times faster than standard circuit breakers.
The current-limiting breakers have the ability to more quickly recognise and react to a short circuit — helping protect equipment from damage and expensive downtime when there is a sudden increase in current.
In areas where there is a high fault, the current-limiting circuit breaker can reduce the energy let through by more than 50% and results in less stress and potential damage to downstream components.
