Features of Eaton Automatic Transfer Switch
- Accessible in three transition types: closed, open in-phase, and open delayed.
- Both automated and manual modes of operation have a double-throw, interlocked power switch powered by a sturdy solenoid operating mechanism.
- Eaton’s Arcflash Reduction Maintenance System offers a service entry-rated option to lower incident energy levels for downstream equipment during maintenance intervals.
- Types of enclosures: indoor and outdoor
- Seismic-approved integrated Cam-Lok receptacle power panel, listed to UL 1008 and CSA 22.2 No. 178, that doubles as a docking station for an instantaneous connection of a portable or temporary generator
Applications of Eaton Automatic Transfer Switch
- Construction of contactors and circuit breakers
- Transition switching between open (time-delayed, in-phase, load voltage decay) and closed
- Isolation bypass functionality
- Remote annunciator and controller for automatic transfer switches (ATS) built-in overcurrent defense
