W94-X112-20 Application Field and Working Principle

Circuit breakers are safety devices used to control electrical circuits from damages caused by overload or short circuit. The W94-X112-20 is a molded case circuit breaker (MCCB) from ABB, a leading global manufacturer of circuit breakers. This particular circuit breaker is designed for industrial applications where high performance is necessary. It offers high rated performance, low noise, and improved wiring flexibility.

Application Field

The W94-X112-20 is a highly flexible and versatile molded case circuit breaker that offers protection against both overload and short circuit conditions. It can be used in a wide variety of industrial applications, including power plants, process control, distribution systems, and more. Its robust design and advanced technology make it suitable for the most demanding applications.

The W94-X112-20 is suitable for use in single-phase and three-phase applications. It can handle up to 4,000 amps of current and is UL certified, meaning it has been thoroughly tested and meets industry safety standards. Additionally, the circuit breaker is RoHS compliant, meaning it is free from heavy metals and other hazardous substances.

Working Principle

The circuit breaker works with a trip mechanism, which monitors and measures the amount of current running through the circuit. If the current reaches a certain level, the trip mechanism will open the circuit and cut off the power supply. This prevents damage to the circuit from an overload or short circuit.

The circuit breaker has an internal trip unit, which is responsible for monitoring the current level. The trip unit is made up of two components: the trip mechanism and the control electronics. The control electronics are responsible for sensing when the current exceeds a certain level and triggering the trip mechanism, which will then open the circuit and cut off the power supply.

The circuit breaker also has a manual reset switch, which allows it to be reset after a trip has occurred. This switch is typically found on the outside of the breaker and must be operated in order to reset the circuit breaker.

Conclusion

The W94-X112-20 is an incredibly versatile circuit breaker designed for industrial use. It has a robust design and advanced technology, making it suitable for the most demanding applications. It is also compliant with industry safety standards and can handle up to 4,000 amps of current. It functions by using a trip mechanism which monitors the current level in order to open the circuit and cut off the power supply in case of an overload or short circuit.
