Allen-Bradley Bulletin 140G moulded-case circuit breakers
Industrial automation users can improve their short-circuit protection with an updated line of current-limiting, moulded-case circuit breakers from Rockwell Automation. The line expands the Allen-Bradley Bulletin 140G moulded-case circuit breakers and claims to offer more comprehensive, fast-acting, short-circuit protection.
The devices protect against overload, short-circuit and ground-fault conditions. They are current limiting and react to circuit overloads two to three times faster than standard circuit breakers.
The updated range can help engineers achieve higher short-circuit ratings in the control panel as a result of their current-limiting ability. In areas where there is a high fault, the current-limiting circuit breaker can reduce the energy let through by more than 50%. This current limitation results in less stress and potential damage to downstream components.
