Circuit Breakers

LELBXK1-39011-80-V application field and working principle

A circuit breaker is a type of electrical safety device designed to prevent electric shock by automatically cutting off the power supply when a short circuit or overload occurs. Specifically, the LELBXK1-39011-80-V circuit breaker is an intermediate to low voltage magnetic/thermal trip circuit breaker designed specifically for the electric power industry, including power plants and electric power distribution. It is a very reliable device, capable of breaking and making normal load current up to 80A.

The main function of a circuit breaker is to protect the electrical system from overload or short circuit where the electric current has surpassed systems thresholds. If a current overload or short circuit occurs, the electric charges are stopped and potentially hazardous situations are avoided. This is done by switching the current off in a matter of milliseconds and thus interrupting the current flow in the circuit.

The LELBXK1-39011-80-V operates by combining a triggering mechanism, usually a magnetic/thermal trip module, with a mechanical operation to interrupt the current. In the event of short circuit or overload, a magnetic trip module senses the current, triggering an electromagnet which causes a mechanical switch known as a trip arm to operate and open the circuit. In addition, the trip arm contains a thermal element to provide added protection against the motor overloading.

The LELBXK1-39011-80-V is particularly suitable for applications in a variety of distributed electric power systems, such as substations and industrial power supplies, as well as consumer markets such as home appliances and consumer electronics. It is especially suitable for areas where frequent operations, such as machinery starts and stops, need to be monitored. The LELBXK1-39011-80-V is also durable, being capable of withstanding environmental temperatures of up to -50°C to +100°C.

In conclusion, the LELBXK1-39011-80-V circuit breaker from Westinghouse Electric Corporation is an effective way to protect electrical systems from short circuits and overloads. With a durable design and wide application range, the LELBXK1-39011-80-V can provide reliable protection for a variety of distributed electrical systems.
