Principle of Energy Storage Switch | Quisure Circuit Breaker

Principle of Energy Storage Switch. 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

The basic principle of a magnetic switch is that an electromagnet (coil of wire) is energized by electricity and then de-energized. When the current is flowing through the coil, it creates a magnetic field which attracts other magnets in its vicinity. When the coil is de-energized and no longer has current running through it, the magnetic field
