Isolating Switch

The Isolating Switch (Knife Switch) is a mechanical electrical isolation device for low-voltage power distribution systems, featuring a visible break point to ensure safety during equipment maintenance. Available in single-throw (1P/3P) and double-throw configurations, it is designed for infrequent manual operations such as power disconnection and circuit isolation. Compliant with GB14048.3 and IEC60947-3 standards, the switch adopts a fully protected design to prevent accidental electric shock, suitable for industrial switchgear, motor control centers, and PV systems. It operates stably in environments with temperatures ranging from -5℃ to +40℃ and altitudes ≤2000m.
