1. The load switch can be disconnected with load and has self-extinguishing function, but its breaking capacity is very small and limited.

2. Isolation switch is generally not capable of breaking with load. There is no arc-extinguishing cover on the structure, and there is also an isolating switch capable of breaking the load, but the structure is different from the load switch, which is relatively simple.

3. Load switches and disconnectors can form obvious disconnection points. Most circuit breakers do not have isolation function, and a few circuit breaker motors have isolation function.

4. The isolating switch does not have protection function. The protection of the load switch is generally protected by fuses, only quick disconnection and overcurrent

5. The breaking capacity of the circuit breaker motor can be made very high during the manufacturing process. Mainly rely on the current transformer to protect the secondary equipment. It can have short circuit protection, overload protection, leakage protection and other functions.
