The Allen-Bradley/Rockwell Automation 173973 spare part is a MOV Field component that is used for digital DC drives from the Bulletin 1395 product line. The Spare Part (SP) series by Allen-Bradley offers a variety of parts for replacement and renewal for devices in the exceptional 1395 product family. These digital DC drives are available in the 4-quadrant armature regenerative and the 2-quadrant variant with a power rating from 1 to 600 Horsepower at 230 to 460 Volts AC. The non-regenerative version includes power ratings ranging from 1 to 30 or 125 to 300 Horsepower at 230 Volts AC and from 2 to 60 and 250 to 600 Horsepower at 460 Volts AC. These drives have standard features such as independently programmable acceleration and deceleration, programmable preset speeds with 5 adjustments, programmable job speeds with 2 adjustments, a programmable MOP (Motor Operated Pot) with 10 adjustments, and options such as a discrete adapter board, a ControlNet adapter board, a node adapter board, and a multi-communication adapter board.
Besides that, the 173973 comes from the 1395 product family that offers accessories such as line reactors and dynamic braking, as well as other features including protective features for overcurrents, overloads, and power losses. The drives are properly protected from an instantaneous overcurrent, the overload of the motor, and also from feedback loss, field economy, and field loss. The optional functionality of the dynamic braking circuitry develops 150 to 200% of the rated motor torque for braking when the function for stopping is initiated. These drives have an open chassis construction and are listed as UL standardized devices which are also approved by the CSA. The 1395 drives and the 173973 operate within a 0 to 55 degrees Celsius (32 to 132 degrees Fahrenheit) ambient operating temperature range and they can be stored in 0 to 65 degrees Celsius (32 to 149 degrees Fahrenheit) temperature range. The 173973 MOV Field has an input voltage rating of 240 to 480 Volts. The surge suppressor of these drives marked with MOV (MOV1 - MOV6) on the power board is intended to be used for protection of armature power bridge from irregularities such as line surges or line voltage spikes.
