Reliable, Low Operating Effort Disconnect Switches
Southern States offers a complete line of single side break group operated disconnect switches. Its easy to install design requires low operating effort and is ideal for sub transmission and distribution applications. In addition, the design philosophy has been adopted for the ES-1 transmission line switch, available in one-way or multi-way configurations.
- Meet all ANSI standards
- Low operating effort
- Minimal maintenance
- Suitable designs for horizontal upright, vertical, or underhung mounting
- 2 insulators per switch
