Structural characteristics of isolation switch

May 29,2025

The isolation switch does not have arc extinguishing capability, 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 in the absence of current in the circuit.

Structural characteristics of isolation switch

No arc extinguishing device: The isolation switch does not have arc extinguishing capability, 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 in the absence of current in the circuit.
Visible disconnection point: In the open state, an insulation gap that meets safety standards is formed between the contacts, and the disconnection state is clearly visible through mechanical structure to avoid misoperation.
