Lighting, ventilation, pumps and heaters on a 208 or 240 V single-phase circuit often just need a simple daily on/off schedule. The Intermatic GMXST-I-240 is a GMX series 24-hour electromechanical time switch with a 208/240 VAC clock motor, a 21 A SPDT switch and 15-minute captive trippers in a UL Type 1 indoor plastic enclosure. A true clock face makes it easy to set.

Why electricians pick it

  • 21 A SPDT contacts rated up to 2 HP at 240 VAC for small motors, fans and pumps.
  • Captive trippers in 15-minute steps cannot fall out and get lost.
  • Manual OFF/AUTO/ON override for service and testing.
  • Finger-safe screw terminals accept up to #12 AWG.
  • Enclosure has spare room for a field-added contactor on larger loads.

Pro tip from the counter

This synchronous model has no battery carryover, so the dial stops during a power outage and the schedule drifts by the length of the outage; on loads where timing matters, add a note on the cover to reset the dial after outages or choose Intermatic's quartz battery-backed GMX model instead.

Best for: 208/240 V lighting circuits, exhaust fans and ventilation, circulation pumps, electric heaters, agricultural loads
