The Allen-Bradley 140G-G2C3-D10 circuit breaker is a 3-pole circuit breaker that comes in the G series of circuit breakers. The main detection mechanism of the breaker is a fixed thermal and magnetic mechanism. This mechanism uses heat and magnets to detect any kind of anomalies in the current, for example, a short-circuit current. With the installation of the Allen-Bradley 140G-G2C3-D10 3-pole circuit breaker in a machine system, operations are safe. The connected equipment and conduits will not suffer damage from short-circuit currents. The breaker has 1 main function that starts with the detection of current and then the performance of a tripping action that will impede the current flow through the conduits. This breaker is commonly used as a control panel switch as well.

The Allen-Bradley 140G-G2C3-D10 3-pole circuit breaker can be put back into operations immediately after the clearing of the fault that caused the interruption, and this is one of the advantages of circuit breakers of fuses. Fuses can be used only once, whereas circuit breakers can work multiple times. The Allen-Bradley 140G-G2C3-D10 3-pole circuit breaker features an interrupting capacity of 25 kA tested at 480 Volts AC voltage. It also comes with a rating of 125 Amps and a rated current of 100 Amps. The users need to consider 2 important facts before installing the breaker. The first thing is the current rating of the unit that is going to be protected by the breaker, along with the voltage and short-circuit currents that are available. The second thing to consider is that the environment where the breaker is going to be installed may affect its performance since one of its detection mechanisms is heat-related.
