W57-XA7A15A10-20

Circuit breakers are important safety devices that protect electrical systems and components from short circuits and overloads. The W57-XA7A15A10-20 circuit breaker is a miniature adjustable molded-case circuit breaker that is designed to protect electrical systems in residential, commercial, and industrial settings.

The W57-XA7A15A10-20 circuit breaker is designed to provide reliable circuit protection from 10 to 15A in residential and light commercial applications. It features an adjustable trip-off setting for overcurrent protection, a mechanical lockout for over-temperature conditions, and a test button for system-level testing. The W57-XA7A15A10-20 circuit breaker is also approved for motor protection in Class 1, Group D, Division 2 hazardous locations.

The working principle of the W57-XA7A15A10-20 circuit breaker is based on thermal-magnetic protection. On the inside of the breaker, a thermal element is connected to the current-carrying contacts which heat up under heavy current. The temperature is monitored by the magnetic switch which activates on a predetermined temperature to break the circuit. The temperature of the thermal element is adjustable and can be set by an adjustment knob on the outside of the breaker.

The W57-XA7A15A10-20 circuit breaker is typically used to protect circuits in residential and light commercial applications such as lighting and fan circuits, air conditioners and other small appliances. It can also be used for motor protection in hazardous locations and provides reliable and cost-effective circuit protection.

The W57-XA7A15A10-20 circuit breaker is designed to provide reliable overcurrent protection, preventing damages to equipment and potential fire hazards caused by electrical overloads. The adjustable trip-off set point allows for customized protection, ensuring the safe operation of electrical circuits and protecting against shorts and excessive currents.

In summary, the W57-XA7A15A10-20 circuit breaker is an adjustable molded-case breaker designed to provide reliable overcurrent protection in residential, commercial, and industrial settings. It works on the principle of thermal-magnetic protection and is suitable for applications such as lighting, fan and air conditioner circuits, as well as motor protection in hazardous locations.
