Bulletin 140G current-limiting circuit breaker now offered by Rockwell Automation



January 30, 2017 – Rockwell Automation says industrial automation customers can improve their short-circuit protection with a new line of current-limiting, moulded-case circuit breakers.

The UL-listed line expands the Allen-Bradley Bulletin 140G moulded-case circuit breakers and protects against overload, short-circuit and ground-fault conditions, according to the company. It adds, these circuit breakers react to circuit overloads “two to three times faster than standard circuit breakers”.

They can help engineers achieve higher short-circuit ratings in the control panel as a result of their current-limiting ability, Rockwell notes, and in areas where there is a high fault, the current-limiting circuit breaker can reduce the energy let through by more than 50%.
