The 140G-G3C3-D12 circuit breaker is an automatic circuit breaker that belongs to the 140G series of circuit breakers that are manufactured and distributed by Allen-Bradley. Circuit breakers have a great variety of applications. This one is intended for automation processes in industrial applications. It can be used as a feeder breaker or as a main circuit breaker or panel switch. In all its possible uses, the interrupting capacity of the breaker must be fully compatible with the loads of current to detect and other things such as voltage and amperage. The Allen-Bradley 140G-G3C3-D12 automatic circuit breaker detects abnormal loads of current that cannot flow in the electric circuit because of the damages it could provoke and short-circuit currents. An abnormal current can start a fire or cause great damage to the equipment.
The Allen-Bradley 140G-G3C3-D12 automatic circuit breaker comes classified as a Frame G breaker. It comes with a size that promotes space-saving and special materials that enable the breaker to operate in humid environments. Its switching class is thermal and magnetic. The breaker combines these 2 switching modes to provide quicker operations. While the bimetal bands detect the amount of current through heat, magnets detect short-circuit currents. External and internal accessories can be added to the Allen-Bradley 140G-G3C3-D12 automatic circuit breaker to improve its functioning and provide a way to mount the breaker. When installing the breaker and after its specifications have been checked, it can be placed in any position and cables rated for 75 degrees Celsius operations need to be included.
