$2,095.00

  • Microprocessor control – Easy-to-use, standard control
  • Programmed transition – Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period
  • Advanced transfer switch mechanism – Unique bi-directional linear actuator provides virtually friction-free, constant force, straight-line transfer switch action during automatic operation
  • Manual operation – Manual operating handles, shielded termination, and over-center contact mechanisms
  • Positive interlocking – Mechanical and electrical interlocking prevent source-to-source connection through the power or control wiring
  • Main contacts – Heavy-duty silver alloy contacts with multi-leaf arc chutes are rated for 100% load interruption
  • Easy service/access – Single-plug harness connection and compatible terminal markings simplify servicing

Description

Cummins PowerCommand 40 Control OTEC Transfer Switch 225A 208V NEMA 3R

The OTEC 208V 225A 3 Phase Automatic Transfer Switch features PowerCommand 40 Control, a microprocessor-based controller with LCD Display and a comprehensive list of functions. Cummins OTEC A066Y108 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 225A 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 225 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 225 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.
