Principle of Energy Storage Switch | Quisure Circuit Breaker

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the

6 FAQs about [Energy storage circuit breaker contact point]

How do circuit breaker contacts work?

These circuit breaker contacts must be moved swiftly and with significant force in order to ensure quick and repeatable make/break times. In order to achieve this rapidity of motion, the breaker is designed to actuate by the stored energy of large mechanical springs.

Where is a contact located in a circuit breaker?

Contacts are found in the arc interruption chamber (in low voltage circuit breakers) and in the vacuum interrupter (in medium voltage vacuum circuit breakers). The contact assembly consists of the movable contact, the movable contact arm, the stationary contact and the stationary conductor.

What is a circuit breaker?

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

What is a circuit breaker contact Assembly?

The contact assembly consists of the movable contact, the movable contact arm, the stationary contact and the stationary conductor. As the circuit breaker opens or closes, the fixed contact moves to close (make) or open (break) the circuit. The contacts are designed to protect against two fault conditions
