Intermatic GM40AV – Frequently Asked Questions

1) Will the Intermatic GM40AV time switch work on 208V or 277V, or do I need a different model for each voltage?
One model covers the range. The GM40AV is an autovoltage time switch rated 120-277 VAC, 60 Hz, so the same unit goes on 120, 208, 240 or 277 volt circuits without ordering a voltage-specific version. For a property manager standardizing timers across buildings with mixed service, that means one part number on the shelf instead of three.
2) What does DPDT mean on the GM40AV and can I switch two separate circuits with it?
DPDT on the GM40AV gives you 2 normally open and 2 normally closed contacts. You can make one load and break another on the same schedule, or run two independent circuits switching together. That is what makes it usable for things like alternating an aerator and a blower, or cutting a fan when refrigeration energizes.
3) How much load can the GM40AV time switch carry?
It is a 40 amp switch, which covers most commercial fan, pump, compressor and merchandiser loads directly without a contactor between the timer and the equipment. Above that rating, run the GM40AV as a pilot device driving a definite purpose contactor instead.
4) How many on/off cycles a day can I program on the Intermatic GM40AV?
Up to 48 ON/OFF operations in a 24 hour period. It is a tripper-style electromechanical clock, and the trippers are captive so they do not fall out of the dial during service. That cycle count is what makes it workable for septic aeration and short repeated ventilation runs, not just a single daily on and off.
5) Does the GM40AV keep time during a power outage?
Yes, it has a self-recharging battery backup that holds the clock through an outage, so the schedule is still correct when power returns. Worth noting the backup maintains timekeeping, not the load contacts.
6) Can maintenance staff force the equipment on without changing the timer schedule?
There is a three-way manual override on the GM40AV: ON, OFF, and AUTO. Flip it to ON to run the load for service or testing, then back to AUTO and the programmed trippers take over again untouched. Power and status LEDs on the front tell you whether the unit is energized and whether the contacts are called.
7) What enclosure space do I need to mount the GM40AV?
Plan for 8.875 inches high, 6.609 inches wide, and 3 inches deep. That depth matters most in a shallow panel run or a crowded mechanical room wall, so check clearance ahead of the conduit layout. Housing is grey.
8) Is the GM40AV a good choice for exercising a standby generator weekly?
Generator exercising is one of the named applications, along with aeration, air movement and ventilation, refrigeration merchandisers, and septic treatment. The DPDT contacts let the same schedule start the exercise and signal or lock out a second circuit at the same time.
9) Should I use an electromechanical timer like the GM40AV or go with a digital time switch?
The GM40AV is electromechanical: a clock dial with physical trippers, no menus to learn. That is the right pick when several people touch the panel, when a tech needs to see the schedule at a glance, and where a simple daily repeat is all the job needs. Go digital instead if you need astronomic (sunrise/sunset) scheduling, 7-day or holiday programs, or different times on different days, none of which a 24-hour dial does.
10) What is the exact part number to order this Intermatic time switch, and where is it made?
Order it as Intermatic GM40AV. Country of origin is Mexico.
