Power circuit breakers | Choosing the Right Circuit Breaker
Numerous factors must be taken into consideration when choosing a circuit breaker. First are the basic electrical characteristics of the equipment involved, such as the following:   Whether it uses an AC or DC current. The voltage, whose determining factor is the highest voltage that can be applied across any two conductors in the circuit. The short circuit current level that will trigger the device to protect it. Other factors include the type...
