Prolong your motors life with a terminal cover!

Our most popular commercial grade motor that mounts on almost any driveshaft to give powerful and quiet control. Takes 24vac or DC, since motor is internally a DC drive motor with microprocessor based circuitry that kills power when motor reaches end of travel-this motor never even gets warm to the touch. 

5 year warranty. 

*Motor is used on our popular "Super Duty" SD series of Round Dampers. Also used on our popular SD3085 Series of Rectangular Dampers.

*Can be adapted to almost any damper using a drive shaft. 

*Uses a fraction of the power of spring return dampers.

* Unique internal circuitry allows "one output control" from any thermostat or single pole switch (no relays needed!), unlike almost any other power open/power close damper motor - you get the best of both worlds, ease of wiring like a spring return, reliability and energy efficiency of a power open, power close 3 wire damper. 

* Uses a single pole, double throw switch with a center off, this motor can be stopped anywhere in its range and will hold position in the airstream for balancing applications

LMB24-3-T Installation Instructions

Pair LMB24-3-T with SPDT Switch to allow modulation for any of our SD series dampers to open, close, or anywhere in between.

The Heavy duty toggle switch is rated at 20 amps at 125 volts (AC) and 15 amps at 250 volts(AC).

A clearly marked aluminum nameplate allows you to easily determine whether you are toggling on or off. The nameplate can be removed or secured with the included nut; ensuring a snug fit to your surface.
