Circuit breakers | Choosing the Right Circuit Breaker
A circuit breaker is an essential safety device for any piece of equipment or network through which an electric current flows. Quite simply it will, as the name indicates, break the circuit and stop the current flowing if it detects any dangerous anomalous current, voltage, or temperature levels in the circuit. Generally, in an industrial context, electricity passes through a circuit-breaker box where it is divided into several circuits. Each of these circuits...
