Circuit Breakers

LELBX1-1-62-10.0-AF-M3-V Application Field and Working Principle

Circuit breaker is an essential element of electrical system that can automatically break the circuit and isolate it, protecting the equipment and personnel from damage or harm. Among all the circuit breakers, LELBX1-1-62-10.0-AF-M3-V, is a kind of low-voltage circuit breaker which adopts hybrid mechanism and has a rated insulation voltage of 5KV, 5000A interruption capability, and a rated voltage of 380V. It features with compact structure, full range of trip characteristics, high breaking capacity, and advanced technical performance. Therefore, it is widely used in all kinds of power circuit for power automation

The working principle of the LELBX1-1-62-10.0-AF-M3-V is quite simple. It has two sets of coils. When the current passing through the circuit breaker is higher than the rated value, the circuit breaker trips, and the current flowing through the circuit will be rapidly reduced. The two sets of coils will be induced by the current and generate an electromagnetic field. This electromagnetic field will attract the armature of the circuit breaker, thus separating the two contact pieces and breaking the circuit. The circuit breaker is designed with two sets of coils in order to reduce the cost. When the current is too high, the first coil will be triggered and cut off the current if the current is still too high, then the second coil will be triggered to cut off the current. Thus, the circuit can be safely isolated.

In addition, a number of features are also provided in the circuit breaker. For instance, the breaking capacity of it can reach up to 5000A, meeting the requirements of the large current system. Its arrangement is also quite user-friendly, the knob can be quickly adjusted to the desired trip characteristics. There is also an auxiliary contacts that can perform various control and operation functions in association with the main contact. Therefore, it can be used in some place that requires a new type of motion control for an electrical system. In conclusion, the LELBX1-1-62-10.0-AF-M3-V circuit breaker is became increasingly popular in the power industry due to its high reliability, automatic operation, and ability to protect electrical devices.
