Description
The Schneider Electric (Square D) 9038DG8 is a heavy-duty mechanical alternator designed to automatically sequence and alternate the operation of two loads — such as duplex pump sets or compressors — ensuring balanced run times, reduced wear, and extended equipment life in commercial and industrial HVAC and mechanical systems.
How It Works
The 9038DG8 mechanical alternator switches control between two motors or loads each time a start signal is received. This alternating action prevents one unit from bearing the full operational burden, distributing run hours evenly across both pieces of equipment. The result is more predictable maintenance intervals and a lower risk of unexpected downtime.
