Overhead Rotary Puffer Switches
Load break with 20kA asymmetrical momentary. G&W's overhead Rotary Puffer (RP) switches are ideal for manual switching or distribution automation applications rated 15.5 and 27 kV, 630 A continuous current requiring up to 20kA asymmetrical momentary. RP overhead switches are designed and tested to applicable IEEE and IEC standards Features:- Economical Package — The manual overhead RP switch is G&W’s most cost effective alternative to traditional gang operated air break switches.
- Ease of Operation — The rotary puffer mechanism is extremely easy to operate whether from a bucket truck or ground level operator. The handle can be padlocked in the open or closed position. Downrod assemblies are available.
- Self-Disengaging Motor Actuator — For applications requiring motor control, an exclusive motor actuator assembly permits easy manual operation if control power is lost. The main shaft automatically disengages from the motor gear assembly after each electrical operation permitting virtually effortless manual operation.
- Visible Open/Close — The color coded main contact position indicator (green-open, red-closed) is easily visible from the ground. The indicator is connected directly to the main contact drive shaft assembly assuring accurate contact status.
