Cummins PowerCommand 40 Control OTEC Transfer Switch 600A 208V NEMA 3R
The OTEC 208V 600A 3 Phase Automatic Transfer Switch features PowerCommand 40 Control, a microprocessor-based controller with LCD Display and a comprehensive list of functions. Cummins OTEC A066Y114 Open Transition transfer switches are a perfect fit for a wide range of commercial and light industrial transfer switch applications.
- Break-Before-Make Switch
- Electrically operated—Mechanically held
- Electrical and mechanical interlocks prevent inadvertent interconnection.
- NEMA 3R enclosure for indoor or outdoor installation.
This 208V 600A Cummins Transfer Switch provides the basic hardware and features required for automatic operation of a standby generator.
Cummins 208 Volt Transfer Switch Control
PowerCommand 40 is a microprocessor controller with LCD digital display, a full list of functions, and tactile soft switches for straightforward operation and navigation. Highlighted controls include PC software configuration with 3 phase sensing on both sources. Manual restore to S1, synchronization check, and event logging. The S-6560 Specification Sheet includes all the benefits and features.
With a programmed transition, switch timing allows the Cummins ATS to disconnect the load from both sources for a programmed time period—especially important for large inductive loads.
Cummins 600 Amp ATS Advanced Mechanism
The ATS mechanism operates electrically with a mechanical hold in the Source 1 and Source 2 positions. Cummins OTEC 208 Volt 600 Amp Automatic Transfer Switch Series 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 and 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.
