Circuit breakers are essential components of the electrical power system. They are responsible for protecting the system from overloading and short circuits of electric components, as well as providing reliable emergency power supply. LELBXPK11-1REC4-52-150.-A-N3-V is a type of circuit breaker designed for alternating current networks and meets the requirements for Industry Standard 60947-2. This article will discuss the application field and working principle of the LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker.

Application Field

The LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker is designed for switching and lifting purposes in alternating current networks with an operating voltage up to 690Vac and an operating frequency up to 50Hz. It is suitable for outdoor or indoor applications, as well as applications with single or double pole configuration. The LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker can also perform tripping and locking duties, protecting the system from overloading and short circuits with a nominal current up to 250A.

Working Principle

The LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker works on the principles of magnetic flux generated by the current in the circuit, an electromagnet which moves the contact between the contactor blocks, and a spring to restore the contact when the current is reduced beyond a certain point. It is an intuitive design that makes it easy for users to understand and operate. When the circuit is overloaded, the increased current causes the electromagnet to pull the contactor out of the contact block, severing the electrical connection and hence preventing any further current from flowing in the circuit. When the current is reduced, the spring pulls the contactor back to its original place, restoring the electrical connection.

Conclusion

The LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker is an ideal solution for small-scale AC networks. Its intuitive operation, reliability, and compact design make it a popular choice among users. As discussed in this article, the LELBXPK11-1REC4-52-150.-A-N3-V circuit breaker is suitable for switching and lifting purposes in alternating current networks with an operating voltage up to 690Vac and operating frequency up to 50Hz, and can perform tripping and locking duties, protecting the system from overloading and short circuits with a nominal current up to 250A.
