High Voltage Load Break Switch

Our High Voltage Load Break Switch provides both load switching and grounding functions. This product covers voltage levels of 10kV, 24kV, and 40.5kV. It bridges the gap between disconnectors and circuit breakers. The switch can close and open load current safely. It does not interrupt short-circuit currents. The FLN36 series uses SF6 gas arc-extinguishing technology. This provides excellent interruption performance. We also offer vacuum arc extinction as an option.

Description

Integrated Switching and Grounding for Distribution

 

Our High Voltage Load Break Switch provides both load switching and grounding functions. This product covers voltage levels of 10kV, 24kV, and 40.5kV. It bridges the gap between disconnectors and circuit breakers. The switch can close and open load current safely. It does not interrupt short-circuit currents. The FLN36 series uses SF6 gas arc-extinguishing technology. This provides excellent interruption performance. We also offer vacuum arc extinction as an option. You can choose based on your specific preferences. The switch is highly integrated in design. It combines the load break switch and grounding switch in one unit. Complete interlocking ensures correct operating sequence. This prevents incorrect operation and enhances safety. The product features a spring charging operating mechanism. Operation modes include local manual operation and remote electrical control.

Compact Design with Reliable Operation

 

This High Voltage Load Break Switch offers rated currents of 630A and 1250A. Rated load breaking current is 630A. Short-time withstand current is 20kA for 2 seconds. The spring operating mechanism stores energy for reliable closing. Even with control power loss, one complete closing operation is still possible. This ensures operation during emergencies. The switch is suitable for various installation scenarios. It works in indoor distribution substations and compact substations. It also fits in ring main units and other distribution equipment. The compact structure saves valuable installation space. This is especially important for projects with space limitations. The ground switch is integrated into the product. It closes after the load switch opens. This grounds the outgoing side for safe maintenance work. The interlocking system ensures the correct operation sequence. It prevents closing the ground switch when the load switch is closed.
