The Allen-Bradley/Rockwell Automation 140G-G2C3-C70 molded case circuit breaker is part of the 140 product line, specifically in the G Frame series. The only requirements to use this circuit breaker in any application are that the voltage, short-circuit current, and the amperage of the unit or conduit are all compatible. The Allen-Bradley/Rockwell Automation 140G-G2C3-C70 molded case circuit breaker is a thermal and magnetic trip circuit breaker. These 2 trip options enable the breaker to protect itself against abnormal currents through the use of 2 metal bars that receive heat generated from the current. The use of magnetic tripping is more specialized for detecting short-circuit current. It has an interrupting capacity of 25 kA.
Besides being used as a protective unit in an industrial application, the Allen-Bradley/Rockwell Automation 140G-G2C3-C70 molded case circuit breaker can also be used as a feeder breaker. This means that the breaker can provide isolation and short-circuit protection for panels and at the same time provide thermal protection for the feeder wires. This way, the breaker also protects different branch wires in the same panel. When the Allen-Bradley/Rockwell Automation 140G-G2C3-C70 molded case circuit breaker is used in unusual conditions, the performance of the breaker will be slightly altered. For example, when the breaker is operating in locations with temperatures below 0 degrees Celsius or above 40 degrees Celsius, the detection and interrupting capacity of the breaker are affected. Another condition that affects the functioning of the breaker is an altitude above 2000 meters. This altitude tends to reduce cooling and dielectric characteristics, thus reducing the efficiency of the detection mechanisms.
