Introduction

Circuit breakers, such as the W58-XA6A4A-3, are protective switching devices used to protect electric circuits against overcurrent, short circuits and grounding faults. The W58-XA6A4A-3 circuit breaker is a three pole-type breaker with a rated current of 400 A and a rated interrupting capacity of 10 kA at 480 V. It is also equipped with adjustable settings for trip characteristics, respond time and features that allow flexibility in designing and configuring the system.

Application Field

The W58-XA6A4A-3 circuit breaker is ideal for use in both industrial and commercial systems. It is designed for use in branch circuits and is suitable for most applications where overcurrent protection is needed. Its high current rating and interrupting capacity make it ideal for applications such as motor starters and short circuit protection in industrial equipment. Its adjustable settings provide flexibility for programming the trips to respond quickly to an overload or short circuit, making it an ideal choice for short circuit protection in sensitive equipment.

Working Principle

A circuit breaker is essentially a switch that is designed to independently disconnect current from a circuit. The W58-XA6A4A-3 circuit breaker operates on the principle of magnetic induction, where electric current flows through a coil which creates a magnetic field. When electric current exceeds the rated limit, this magnetic field builds up and trips a set of contacts, opening the circuit and stopping the flow of current.In the W58-XA6A4A-3 circuit breaker, the trip system consists of a thermal magnetic trip unit, which is a combination of two separate trip elements - a thermal element and a magnetic element. The thermal element senses changes in the current which in turn cause a bimetallic strip to deform and move a set of dissimilar metals against each other, breaking the current. The magnetic element senses changes in the current which cause an electromagnet to be energized, functioning like a relay and breaking the current. When either the thermal element or the magnetic element trips, a “trip open” message is displayed on the circuit breaker giving an indication to the user that tripping has occurred.

Conclusion

The W58-XA6A4A-3 circuit breaker is an effective overcurrent and short circuit protection device. Its adjustable settings provide flexibility in programming the trips for reliable and fast response, making it ideal for sensitive equipment short circuit protection. Its rated current and interrupting capacity make it ideal for motor starter and other similar applications.
