The Allen-Bradley 140G-G2C3-C32 molded case circuit breaker is a compact industrial-based circuit breaker with a fixed thermal-magnetic trip unit designed to provide short-circuit and thermal overcurrent protection to conductors, equipment, branch circuit, and main conducting circuits. The 140G-G2C3-C32 circuit breaker is rated for HACR (Heating, Air Conditioning, and Refrigeration) use, and it can also be used as a disconnecting device for most control panel applications. The 140G-G2C3-C32 circuit breaker has a continuous current rating of 125 Amps, and a 25 kiloamps breaking capacity rating at 482 Volts AC. It is ideal for circuits with 600 Volts AC per the UL/CSA rating, and it has an 800 Volts AC insulation voltage rating. The 140G-G2C3-C32 circuit breaker has an 8 kilovolts AC withstand rating and a mechanical lifespan of up to 240 operations per hour. It has a thermal trip rating of 32 Amps and a magnetic trip rating of 500 Amps.

The 140G-G2C3-C32 circuit breaker has a 3-pole design with bolt-on line/load terminals, and it has standard 32-inch pig-tail wiring terminals for internal accessory termination. The 140G-G2C3-C32 circuit breaker has a fixed thermal and magnetic trip unit made of a bimetallic element strip and electromagnet coil. These trip elements provide fast-acting and instantaneous trip action when the line current exceeds the set value. The 140G-G2C3-C32 circuit breaker has a trip-free operating mechanism that opens and closes the circuit breaker’s contact, and a rotary switch that indicates the breaker’s position. It has a 40 degrees Celsius temperature limit without de-rating and it is installed on a DIN rail. The 140G-G2C3-C32 circuit breaker has aggregate dimensions of 76.2 x 70 x 130 millimeters, and it weighs approximately 1.1 kilograms.
