Circuit Breakers

A circuit breaker is an important electrical device mainly designed to protect electrical circuits from overload or short circuit fault conditions. It is one of the most essential components used in electrical systems. This article is about UPL1-22486-7, a circuit breakers, and its application fields and working principle.

UPL1-22486-7 Application Field

UPL1-22486-7 is a circuit breaker manufactured by Schneider Electric, which is used in many types of industrial applications, such as welding station, ovens, furnaces and motors. It is especially suitable for medium voltage AC system up to 3,000V. It is also compatible with Schneider Electric’s full range of contactors and contactor/overload relays. The UPL1-22486-7 circuit breaker features a robust construction with UL/IEC approval, ample contact spacing for high-short-circuit current protection, and a number of operation modes including adjustable trip current.

Working Principle

The working principle of UPL1-22486-7 is based on the amperage flow/load sensing principle. The device consists of a series of moving components, such as the trip element or the terminal base, which are connected to two movable contacts. The contact between the two movable contacts is sensed by an electromagnetic field. When the amperage flowing through the contacts increases, the electromagnetic field will increase in strength. This will cause the two contacts to separate, and the circuit breaker will open the circuit.The resetting of the circuit breaker can be done manually by pressing the reset button. It can also be done automatically, using a reset relay. The reset relay decreases the current through the contacts by releasing the two contacts. It then applies a non-contact machining voltage to the contacts, allowing them to close without burning them out.

Conclusion

UPL1-22486-7 is a circuit breaker manufactured by Schneider Electric, and it is mainly used in industrial applications. The working principle of the circuit breaker is based on the amperage flow/load sensing principle. The resetting of the circuit breaker can either be done manually by pressing the reset button, or automatically by using a reset relay. The UPL1-22486-7 circuit breaker features a robust construction, ample contact spacing for high-short-circuit current protection, and a number of operation modes.
