Variable-frequency drive
A variable-frequency drive supplies a controlled-frequency motor output.
In plain English
SR33-132 is the drawing identifier for motor drive or starter in AutomationDirect's Soft Starters collection. A motor drive or starter controls the operation of its connected motor in the way stated by the selected equipment documentation. Its electrical behaviour is not defined by the enclosure outline.
For example, in a microgrid installation with a plant panel controlling a fan or pump motor, use the SR33-132 reference to coordinate power terminals, control interfaces, ventilation and service access. Show the neighbouring equipment and the connection route so the installer can understand the intended arrangement.
Use the reviewed native drawing identified as Drives-Motors-Motion/Compact Soft Starters/SR33-132.dwg for the exact physical details. Locate the named file in its original manufacturer archive. Manufacturer drawing previews are shown only when an exact approved source is available. Any illustrative 3D view is a separate concept and is not to scale; use the selected manufacturer documents for dimensions, ratings and installation details.
