The GM40 Series 40 Amp Auto-Voltage Time Switch is a universal electromechanical control, which automatically detects the input voltage without the use of a DIP switch or selector pins. The time switch automatically selects any voltage between 120 VAC and 277 VAC. The time switch controls high amperage loads for lighting, HVACR, pumps, motors, fan controls, access controls, agricultural facilities, and general purpose electrical circuits. The mechanism is mounted in a compact UL Type 3R outdoor enclosure and features a DPDT Switching Configuration standard.
