The 140G-G2C3-C45 thermal-magnetic circuit breaker is a molded case circuit breaker from the Allen-Bradley 140G, Frame G circuit breaker family that is designed to protect the conductors and equipment from thermal and electrical overloads. The 140G-G2C3-C45 circuit breaker features both thermal and magnetic trip units that provide instantaneous trip action via electromagnetic and bimetallic heat elements, it comes with field-installable accessories that make it easy to use and install. The 140G-G2C3-C45 circuit breaker is rated at 125 Amps of current, and it is designed for applications with 600 Volts AC maximum operating voltage. The 140G-G2C3-C45 circuit breaker has an interrupting rating of 25 kiloamps, and a rated withstand voltage of 8,000 Volts AC (8.0 KV). The 140G-G2C3-C45 circuit breaker has a maximum thermal trip current rating of 45 Amps and a magnetic trip current rating of 500 Amps. The 140G-G2C3-C45 circuit breaker has a mechanical lifespan of 240 operations per hour, and an electrical lifespan of 8000 operations at 415 Volt AC. The 140G-G2C3-C45 circuit breaker has a thermal-magnetic trip unit with a non-adjustable trip setting that provides fast-acting and instantaneous trip action by using a bimetallic strip element and an electromagnetic coil.
The 140G-G2C3-C45 circuit breaker has a bimetallic element that deflects heat as the ambient temperature around the element increases, causing a trip action. It has a 3-pole design and comes with standard end-cap line and load terminals. The 140G-G2C3-C45 circuit breaker has an operating mechanism that closes and opens the breaker’s contact, and a pig-tail wire terminal as a standard termination for the internal accessories. The 140G-G2C3-C45 circuit breaker has IP 40 and IP 20 ingress protection ratings, and a maximum operating temperature of 40 degree Celsius without de-rating. It has a net shipping weight of 2.42 pounds, and dimensions of 3 x 2.75 x 5.12 inches.
