SF400 Application
The SF400 is a completely self-contained electric-motor-driven switch operator utilized to automatically and/or remotely control several styles and types of transmission or substation switches. Switch and operator can be mounted on wood, concrete or steel poles and/or substation structures; either new or retrofit installations.

Select from a swing handle or worm-gear hand crank for manual operation. A safety interlock prevents operator engagement when the crank handle is installed. Safety guards are standard on motor-drive-train for maximum personnel safety.

The SF400 operator comes standard with eight (8) Auxiliary Switch Cams for customer use. Additional contacts are available. These finger tip adjustable cam contacts provide additional functionality for the operators, especially important in the SCADA-interfaced operating environment of today. Terminal blocks are conveniently located on either side of the cabinet, just inside the door.

Environmentally Qualified
The SF400 operator has successfully completed environmental tests. It is suitable for application in a temperature range of -40º F to +160º F. Two, 200 watt heaters with adjustable thermostat reduce moisture and condensation concerns inside the welded aluminum cabinet.
