W31-X1016-5

Circuit breakers are essential components of the electrical grid. They are designed to protect the electrical system during abnormal conditions such as a short circuit or overloading. The W31-X1016-5 is a type of circuit breaker. This article will discuss its application field and working principle.

Application Field

The W31-X1016-5 circuit breaker is mainly used to protect medium-sized transformers. It is suitable for mild overload and low-level short circuit protection in three-phase power systems. As a three-pole synchronous switch, it can be used to control an AC load, thus making it suitable for multiple applications such as the primary protection of electrical and power equipment, the control of AC motors, and the improvement of power quality. Recently, the W31-X1016-5 circuit breaker has become the most widely used circuit breaker for medium-sized transformers.

Working Principle

The W31-X1016-5 circuit breaker has three poles grid - one active pole, one neutral pole, and one earth pole. In normal operation, the current flows through the active pole and the neutral pole to reach the neutral line. When an abnormality occurs, such as an overload or a short circuit, a signal will be sent to the circuit breaker, activating the breaker and trip contacts. This cuts off the line current, thereby protecting the transformer and the entire electrical system.

Conclusion

The application field and working principle of the W31-X1016-5 circuit breaker were discussed in this article. This circuit breaker is designed to protect medium-sized transformers. It can be used to control AC loads, and it is suitable for mild overload and low-level short circuit protection in three-phase power systems. When an abnormality occurs, the breaker trips, thereby protecting the transformer and the entire electrical system.
