Switch with confidence under all system conditions with the Load and Line Switcher Family
The Southern States innovative LLS® Load & Line Switcher switch attachments add reliable and cost effective load breaking, loop splitting, and line dropping capability to group operated disconnect switches. In addition to working with the Southern States family of vertical break and type ES-1 side break switches, the LLS® adapts to most other manufacturer’s disconnect switches and can be purchased directly from the switch manufacturer or as a kit from Southern States for field retrofit. The LLS® is also well suited for use in transformer magnetizing current interrupting, and cable switching applications.
- Single gap SF6 puffer interrupters insure disturbance free switching of loads, lines, power transformers, cables, buses, and reactors
- 2000 full load operations with no maintenance
- Shipped fully pressurized and ready for installation
- Factory high potential testing eliminates need for field test
- Visual dielectric indication via a color coded, temperature compensated gauge provides confident switching and enhanced personnel safety
- Can be mounted on horizontal upright, vertical mount, and phase-over-phase side mounted vertical break disconnects
