Structural characteristics of isolating switches

No arc extinguishing device: The disconnector does not have the ability to extinguish arcs, so it cannot be used to cut off or connect load current and short-circuit current. Its design purpose is only to provide reliable physical isolation when the circuit has no current. Visible disconnection point: In the disconnected state, an insulation gap that meets safety standards will be formed between the contacts, and the disconnected state can be clearly seen through the mechanical structure to avoid misoperation.
