SPC Series Plug Cutout Type S-1

The SPC Series Plug Cutout Type S-1 is a device installed at the constant current regulator (CCR) output through which the series circuit passes. With the handle assembly removed, the SPC isolates the CCR output from airfield series loop for maintenance personnel safety. The SPC also shorts the series loop and shorts the regulator secondary aiding in maintenance checks and troubleshooting.

Primary power to the CCR should always be shut-off and locked out before removing the handle assembly.
