Confident switching for loads, loops, and lines

These factory-tested attachments upgrade disconnect switches with reliable load breaking and line dropping capabilities.

The Southern States LLS® Load & Line Switcher attachments enhance standard group-operated disconnect switches with dependable load interrupting, loop splitting, and line dropping performance — even under demanding system conditions. Designed for easy integration, the LLS® works not only with Southern States vertical break and ES-1 side break switches, but also adapts to many other manufacturers’ disconnects. Customers can order LLS® units directly through the switch supplier or as a retrofit kit from Southern States.

Beyond basic line switching, the LLS® excels in applications such as transformer magnetizing current interruption and cable switching — offering both operational flexibility and long-term value.
