Load switches, High Voltage Disconnect Switch, isolating switches, and circuit breakers all carry the rated current of the circuit in the primary circuit. In short, the circuit breaker is used to protect the circuit, the load switch can disconnect and connect the normal load current of the system, and the role of the isolating switch cannot be ignored. The isolating switch plays the role of an obvious disconnection point in the circuit to ensure the safety of maintenance personnel. Let's take a closer look at their functions and differences.
