What are the Differences Between Load Switches and Disconnectors?
1. They cut off different currents.
Because the disconnecting switch has no arc extinguishing device, so only suitable for cutting off the current without load, can not cut off the load current, short circuit current, so the disconnecting switch appliance can only be operated safely in the case of the circuit disconnect, and is rigorous with load operation, so as not to cause safety accidents. Load switch because of arc extinguishing device, so can overload current and rated load current, but the same can not cut off short circuit current.
2. The load switch has arc extinguishing device, but the disisolating switch does not have such device.
The arc extinguishing device is to be able to better help to switch appliances open and closed, but also can effectively limit the arc, help arc extinguished. With such an arc extinguishing device, it is safer for switching appliances. So most of the switch appliances inside are by the arc extinguishing device. Especially household switching appliances.
3. They have different functions.
Because there is no arc extinguishing device, the isolating switch can only be applied to the high-voltage circuit device which needs to be live and the part which needs to be cut off for an isolation function, so as to ensure the maintenance and inspection of the high-voltage circuit and ensure the safety of personnel.
The load switch is applied to stationary high voltage equipment, which can cut off the fault current and rated current in high voltage equipment, so the two functions are different, but both are applied to high voltage equipment.
