The Allen-Bradley 140G-G6C3-C30 circuit breaker is a 140G molded case circuit breaker. This is a complete circuit breaker that needs no additional modules to operate. It has integrated fixed thermal and magnetic trip units. This device is intended to protect electrical circuits that are operating with a current of less than 30 Amps, which is the set current limit of this device. The 140G-G6C3-C30 circuit breaker has a G frame housing with a 125 Amps rating with 3 poles. Its interrupting rating is 65 kA at 480 Volts AC. Its ultimate breaking capacities are 100 kA at 220 Volts AC and 70 kA at 500 Volts DC (with the terminals connected in series). The dimensions of this 140G molded case circuit breaker are 5.19 inches in height, 3.00 inches in width, and 2.75 inches in depth. The 140G-G6C3-C30 circuit breaker weighs 2.42 pounds (1.1 kilograms). The thermal trip value of the device is 30 Amps and the magnetic trip value is 500 Amps.

If interventions or any adjustments are required on the device, in order to avoid the possibility of injury or damage, it is necessary to disconnect the power supply at the input side. The 140G-G6C3-C30 circuit breaker is designed to accept 14 AWG wires, and it has a DIN-rail mounting option as a standard mounting option. It is a factory-assembled device in a plastic supporting housing that is very often used as the main disconnecting means for an industrial automation control panel. The users can manually disconnect the power on the output side of the circuit breaker by pulling the main handle to the “0” position. The operating temperature range of the 140G-G6C3-C30 circuit breaker is 0 to 40 degrees Celsius.
