GMB63H3PC2 is a type of circuit breaker manufactured by Schweitzer Engineering Laboratories, Inc. that is designed to protect electrical circuits from overload and short-circuit conditions. It is a three-phase circuit breaker that can be used in both residential and commercial applications and is UL listed and CSA certified. This article will outline the application fields and working principle of the GMB63H3PC2 circuit breaker.

Application Field:

The GMB63H3PC2 circuit breaker is designed to provide protection for three-phase circuits. It is UL listed and CSA certified for use in industrial, commercial and residential applications. This includes motor circuits, lighting circuits, receptacles, transfer switches and other general-purpose circuits. It can be used in conjunction with other types of circuit breakers, such as thermal-magnetic, electronic and molded case breakers, to provide further protection.

Working Principle:

The GMB63H3PC2 circuit breaker works on a simple principle. It is designed to open the circuit if an overload or short-circuit condition occurs. This is done by sensing the current in the circuit and, if necessary, opening the contacts to break the circuit. The breaker is designed to close again after the fault is removed and the current returns to a safe level.

The GMB63H3PC2 circuit breaker also includes a trip unit, which contains an adjustable current limit. The current limit is set by adjusting a dial on the unit, allowing the current flowing in the circuit to be limited to a safe level. This helps to protect the circuit from overheating due to an overload or short-circuit condition.

The GMB63H3PC2 also includes an internal overvoltage protector. This device monitors the voltage of the circuit and will open the circuit if it exceeds a predetermined level. This helps to protect the circuit and any equipment connected to it from electrical damage due to high voltages.

The GMB63H3PC2 circuit breaker can also be used with a ground fault circuit interrupter (GFCI) device. This device will open the circuit if it detects a difference in the current flow between the line and the neutral wires. This helps to protect people from electric shock if they come into contact with an electrical circuit that has an imbalance in the currents.

Conclusion:

The GMB63H3PC2 is a three-phase circuit breaker that can be used in both residential and commercial applications. It is designed to open the circuit if an overload or short-circuit condition occurs and it also includes features such as an adjustable current limit and an overvoltage protector. The ability to use the breaker with a GFCI device further adds to its safety features.
