The Allen-Bradley 140G-G3C3-C60 circuit breaker is a molded case circuit breaker (MCCB) that features thermal and magnetic trip mechanisms. It is included in the Allen-Bradley 140G series of molded-case circuit breakers. This mechanism enables the breaker to detect abnormal currents and perform an interrupting action that will stop the current flow from causing further damages.  This breaker can be applied as the main breaker and as a feeder circuit breaker, depending on the application requirements. The Allen-Bradley 140G-G3C3-C60 molded case circuit breaker (MCCB) comes with 3 poles and a rated current of 125 Amps. The interrupting capacity of the breaker is 35 kA (based on 480 Volts AC) and it comes with a current range of 60 Amps. One of the attractive features of the breaker is that it comes with high interrupting and breaking capacities AND at the same time provides saves space and comes manufactured in anti-corrosion and anti-condensation materials.  

The Allen-Bradley 140G-G3C3-C60 molded case circuit breaker (MCCB) is composed of more than 1 accessory. Among its external parts, it has standard end cap terminals, multi-cable terminal lugs, and extended phase barriers. It also has internal accessories such as auxiliary and alarm contacts, shunt trips, and a UV relay. When installing the Allen-Bradley 140G-G3C3-C60 molded case circuit breaker (MCCB), cables rated for operation temperatures between 50 and 60 degrees Celsius are recommended and the breaker can be mounted in different positions without altering its general functioning, but it is necessary to know local plant regulations before mounting the breaker. This unit is sensitive to extremely high temperatures and its performance might be affected by excessive heat.
