The Allen-Bradley 140G-G2C3-C15 circuit breaker is designed and manufactured as part of the Bulletin 104G MCB series of industrial circuit breakers.

It is a molded case circuit breaker and a fixed thermal and fixed magnetic type circuit breaker.The 140G-G2C3-C15 circuit breaker supports a 15 ampere current rating,

The 140G-G2C3-C15 circuit breaker supports a 15 ampere current rating, a 15 ampere thermal trip rating, and a 500 ampere magnetic trip rating. The circuit breaker is also available in a 3-pole configuration. 140G-G2C3-C15 circuit breakers come standard with end caps or bolt-on material.

About Allen-Bradley The 140G-G2C3-C15 Molded Case Circuit Breaker is a thermal magnetic circuit breaker in the 140G circuit breaker series designed to provide short circuit protection for a variety of control panel applications.

As with all 140G circuit breakers, the 140G-G2C3-C15 circuit breaker is sized in accordance with Table 430-152 of the NEC (National Electrical Code).

The 140G-G2C3-C15 circuit breaker is suitable for branch or main circuits operating at 600 volts AC (690 volts IEC).

It has a breaking capacity value of 25 kA (480 VAC) and a current rating of 125 amps.

The 140G-G2C3-C15 circuit breaker has a fixed thermal/magnetic trip device with fixed thermal and magnetic trip ratings of 500 amps and 15 amps, respectively.

The breaker will trip immediately when the current flowing through the breaker exceeds the breaker’s setting.

The 140G-G2C3-C15 circuit breaker provides thermal trip action through the use of its bimetallic element, which deflects high currents when they flow through the circuit for extended periods of time.

It also provides magnetic tripping action by means of a solenoid coil which provides a magnetic field proportional to the current applied to the circuit, thereby tripping the circuit when the current exceeds the set trip value.

The 140G-G2C3-C15 circuit breaker has a rated life of 25.000 operations (240 operations per hour) and an electrical life of 8.000 operations (120 operations per hour).

It has 3-pole wiring with line and load side terminals. It comes standard with 1 meter pigtail terminals for mounting internal accessories.

The 140G-G2C3-C15 circuit breaker is DIN rail mounted and is rated IP 20 or IP 40.

The 140G-G2C3-C15 circuit breaker is calibrated for an ambient enclosure temperature of 40 degrees Celsius and can be stored over a temperature range of -40 to 80 degrees Celsius.

The 140G-G2C3-C15 circuit breaker weighs approximately 1.1 kg and has overall dimensions of 76 x 70 x 130 mm.

140G-G2C3-C15 Technical Description

The Allen-Bradley 140G-G2C3-C15 molded case circuit breaker has a G frame and 125 amps. It also has a 25 kA breaking rating and 3 poles.
