UPGN666-34558-1 Circuit Protection

Circuit breakers are electrical devices designed to protect an electrical circuit from damage due to overload or short circuit. They are commonly used in residential, industrial and commercial applications, and are designed to disconnect the power supply to an electrical circuit when the load exceeds a certain limit. The UPGN666-34558-1 circuit breaker is a type of circuit breaker that is designed to provide an automatic shutdown in the event of an overcurrent or short circuit. It is commonly used in industrial applications, but can also be used in residential and commercial applications.

The UPGN666-34558-1 circuit breaker is a two-pole, three-phase circuit breaker with a maximum capacity of 600A. It is designed to disconnect the power supply when the load exceeds 25 percent of the maximum capacity. The circuit breaker features an adjustable trip current which can be set to a range from 10-600 amperes. It is also equipped with an adjustable overload shutoff feature that can be used to further increase the safety and protection of an electrical circuit.

The working principle of the UPGN666-34558-1 circuit breaker is relatively simple. When the current flowing through the circuit exceeds the predetermined over-Current protection level, the thermal trip element in the circuit breaker heats up and expands. This causes the trip contacts to open, which disconnects the power supply to the circuit and prevents further damage.

The UPGN666-34558-1 circuit breaker has a wide range of applications. It is commonly used in industrial applications such as power plants, factories, and shipyards for controlling high voltage equipment. It is also used in residential and commercial applications such as homes and offices. The circuit breaker is also used to protect lighting and electrical appliances in public areas such as theatres, shopping centres, and airports.

In conclusion, the UPGN666-34558-1 circuit breaker is a two-pole, three-phase device designed to provide an automatic shutdown in the event of a overload or short circuit. It has a wide range of applications in industrial, residential and commercial applications and is designed to disconnect the power supply when the load exceeds 25 percent of its maximum capacity. The circuit breaker works by heating up and expanding its thermal trip element which causes it to open and shut off the power supply.
