This 480V 3-Phase 225A Cummins ATS OTEC Transfer Switch provides the basic hardware and features required for automatic operation of a standby generator.
Cummins OTEC Transfer Switch Advanced Mechanism
The ATS mechanism operates electrically with a mechanical hold in the Source 1 and Source 2 positions. Cummins OTEC 480-Volt 225-Amp Automatic Transfer Switches perform a break-before-make action while electrical interlocks prevent interconnection of the normal and emergency signals. High pressure silver alloy contacts resist burning or pitting; arcing surfaces protect the main contacts. Multiple leaf chutes cool and quench arcs, further protecting the contacts. A protective cover allows inspection while preventing accidental contact with energized surfaces.
UL-1008 certification, including the contact assemblies, covers applications requiring high endurance switching capability for the life of the ATS.
