W57-XB7A4A10-20 Application Field and Working Principle

The W57-XB7A4A10-20 is a type of circuit breaker, which is typically applied in low-voltage distribution equipment originating from China. It is composed of four parts: contact, arc extinguish chamber, operating mechanism, and enclosure. The working principle of the circuit breaker is associated with the electrical contact, which is opened and closed when the current is initiated or interrupted. The operation mechanism will be activated when a pre-determined overload or short circuit current is detected. The contact then drops away from the starting position, and an arc is created between the two contacts. As the arc contacts then break away, an arc extinguishing chamber is used to disperse the current from the existing arc.

Classification of Circuit Breaker

A circuit breaker can be classified based on the purpose of its application. Depending on the situation, they can either be short circuit breakers, current limiting breakers or circuit protectors.

Short Circuit Breakers

Short-circuit breakers are applied when a higher than normal current is detected in a circuit, for instance when a short-circuit occurs. As soon as the circuit is disconnected, these breakers immediately shut off the current from the electrical circuit. This can address an overcurrent situation which would otherwise lead to a catastrophic event.

Current Limiting Breakers

As the name implies, current limiting breakers are installed to limit the current in an electrical circuit. They are typically applied in applications with high electrical loads, and help to protect the source from high loads. Since the breaker limits the flow of current, it also helps to prevent damaging high-current situations.

Circuit Protectors

Circuit protectors are used to protect electrical systems from a fault or short circuit situation. These breakers will detect a current that is higher than a pre-determined limit and then quickly disconnect the circuit. Depending on the application, these breakers may be used to protect an array of electrical equipment, including motors, lights, pumps, controllers and other electric components.

The W57-XB7A4A10-20 Circuit Breaker

The W57-XB7A4A10-20 circuit breaker is applied in low-voltage distribution equipment. This breaker is composed of contact, arc extinguish chamber, operating mechanism and enclosure. The contact is opened and closed when there is an initiation or interruption of current. When an overload or short circuit current is sensed, the circuit breaker will be activated and the contact then drops away from the starting position. The arc-interrupting chamber will be used to disperse the arc current from the existing arc. The W57-XB7A4A10-20 circuit breaker is a great solution for any low-voltage application and provides efficient protection against short-circuits, overloading and other electrical issues.
