How does Circuit Breakers Work?
-5℃~40℃
It consists of a bimetallic strip and a plunger arrangement inside. Also, there is a latch arrangement made to hold the contacts closed, when it is turned ON.
Heated Up
The bimetallic strip is designed to carry a specific amount of current through it. When the current flowing through it exceeds the limit, the bimetallic strip gets heated up and it bends.
As it bends, it knocks down the latch holding the contacts. Higher the current faster shall be the operation.
Maximum Limit
Similarly, during short circuits, the current flowing through the miniature circuit breaker shall be several times the maximum limit.
Opens the Contacts
This activates the plunger arrangement instantaneously, which in turn knocks down the latch and opens the contacts. This is how a miniature circuit breaker works.
As one of switch socket manufacturers, we will do our best to meet all the needs of customers.
We can also offer types of electrical wiring devicesfor sale, if you are interested, please leave us a message.
