The 140G-G2C3-C20 molded case circuit breaker by Allen-Bradley is a G frame circuit breaker with a fixed thermal-magnetic trip unit designed for short-circuit protection in industrial control panel applications. This circuit breaker features both thermal and short-circuit protection, and it comes in a compact 3-pole design with easy field-installable accessories for simplified use. The 140G-G2C3-C20 circuit breaker has a fixed thermal rating of 20 Amps. It has a 125 Amps current rating and a breaking capacity of 25 kiloAmps (maximum) at 480 Volts AC. The 140G-G2C3-C20 circuit breaker is designed for a 600 Volts AC circuit (per the UL/CSA standards). It has an insulation voltage rating of 800 Volts, and a rated impulse withstand voltage of 8 kilovolts (KV). The 140G-G2C3-C20 circuit breaker has up to 25,000 operations in its mechanical lifespan, and an electrical life span rating of up to 8,000 operations.

The 140G-G2C3-C20 circuit breaker has a fixed thermal-magnetic trip unit that is made up of a bimetallic heat element and an electromagnet coil in series with the line load. This trip element provides instantaneous thermal trip actions when the current load exceeds the factory designated value. The 140G-G2C3-C20 circuit breaker has an operating mechanism with a hand toggle that can be used to control the breaker’s contact, and this toggle can also be used to indicate the breaker’s position (ON, OFF, or TRIPPED). It is mounted on a DIN rail, and it comes with IP 20 or the IP 40 ingress protection ratings. It is rated 80% efficient, and it has a temperature limit of 40 degrees Celsius. The 140G-G2C3-C20 circuit breaker weighs 1.1 kilograms, and it has dimensions of 76.2 x 70 x 130 millimeters.
