Circuit Breakers Introduction

A circuit breaker is an electrical device that disconnects or interrupts an electrical circuit on overload, short circuit, or other system fault conditions. As the name implies, they can be reset to resume normal operation. Circuit breakers are widely used in industrial, commercial, and residential applications. Circuit breakers provide an easy way to shut off power when a fault is detected without requiring the user to manually switch the power off and on.

UPGH666-23376-19

UPGH666-23376-19 is a type of circuit breaker designed for the specific purpose of protecting high-amperage loads. It is typically used in larger industrial and commercial applications such as panel-mounted switches, power distribution systems, and motor starter switches. The UPGH666-23376-19 is a three-phase device that can be used in both single and three-phase connections. It features a high-current rating of 5,000 amps and a short-circuit rating of 10,000 amps.

Application Field of UPGH666-23376-19

The UPGH666-23376-19 is mainly used in large industrial and commercial applications that require high-amperage protection. It is most commonly used in the protection of large motors, such as in the motor control centers of industrial facilities, as well as in the protection of large transformers. It is also used in the protection of high-load circuits and power distribution systems.

Working Principle of UPGH666-23376-19

When the current of the circuit exceeds the predetermined rating of the UPGH666-23376-19, the circuit breaker trips and opens the circuit in order to protect the electrical system from damage due to an overload or short circuit. When the fault condition is no longer present, the breaker can then be reset by a qualified technician to restore power to the circuit.

The UPGH666-23376-19 features a pressure-responsive phase-compensating trip unit that measures the three-phase current of the circuit being protected. The internal mechanism of the trip unit is designed to respond to current flow in the circuit and to release an exceptionally high surge of energy when a fault is present. This energy release is what trips the breaker and opens the circuit.

Conclusion

The UPGH666-23376-19 is a type of high-amperage trip breaker designed specifically for large industrial and commercial applications. It is a three-phase device that can be used in both single and three-phase connections and features a high-current rating of 5,000 amps and a short-circuit rating of 10,000 amps. The UPGH666-23376-19 is designed to open the circuit in the event of an overload or short circuit to protect the electrical system from damage. The internal mechanism of the trip unit responds to current flow in the circuit and releases a surge of energy when a fault is detected, thus tripping the breaker and opening the circuit.
