Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the Allen-Bradley Bulletin 140G molded-case circuit breakers and offers more comprehensive, fast-acting, short-circuit protection.
线路扩展可防止过载，短路和地面故障条件。新的断路器线路断路器是UL-CULLID限制，并反应电路超过标准断路器快两到三倍。
“虽然所有模压式断路器提供了一些能量限制，但我们的新电流限制选项是一种高性能的断路器，”罗克韦尔自动化全球产品经理Scott Lasko表示。“这些限流断路器具有更快地识别和对短路造成和反应的能力 - 当电流突然增加时，有助于保护设备免受损坏和昂贵的停机设备。”
The new line 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 percent. This current limitation results in less stress and potential damage to downstream components.
