Click on:LMB24 Kit 3 to see our Belimo to Trol A Temp and EWC kit that replaces this motor with a modern industry standard Belimo LMB motor, better motor at less cost, with more features!
This Honeywell MSTN motor is a 2 Position, power-open, power-close actuator. Used on old-style, standard opposed blade rectangular dampers sold by EWC, Trol A Temp, and Honeywell Trol a Temp.
Round dampers with this motor require a different motor with 45 degree travel. For application questions, message us via Ebay. The MSTN, power open, power close actuator used with old-style, standard opposed blade dampers. MSTN actuators are only interchangeable with other MSTN or EWC MAN style eight terminal motors.
This motor is interchangeable with the Honeywell MSTN motor for Trol-A-Temp or Trol-A-Temp dampers, and EWC Rectangular dampers used with the same eight terminal motor. 24-volt (AC), 6 Volt Ampere (VA), 50- 60-cycle, two-position motor actuator used with all Honeywell AOBD, AOBD-BM, and IOBD automatic opposed blade dampers. MSTN is a uni-directional motor that requires Single-Pole, Double-Throw (SPDT) switching to drive the damper open and closed, common in most zone control panels. It uses a wafer switch to power the synchronous motor for only 30 seconds while the motor is moving between open and closed or vice-versa. When the motor reaches the open or closed position, the internal switches cut off power to the motor. This ad is for the motor only, and not the linkage that drives the blade. These older style dampers used no blade bushings and can rattle, or have problems with the non replaceable drive linkage. Due to the high parts cost of the replacement motors, these dampers can be replaced with many different brand newdampers from our Damper Direct store, contact us via Ebay messages for more information, and we will support you on how to install and wire, which is very easy, even on the original trol a temp panels.
