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.
