CONTACTOR BASED AUTOMATIC TRANSFER SWITCHES
Contactor-Based Transfer SwitchesA critical component of any emergency power system, Eaton's contactor based automatic transfer switch quickly and safely shifts the load circuit from a normal power source to the emergency source, permitting critical loads to continue running with minimal or no outage in momentary losses of power. Designed with operational simplicity in mind, the compact design and user friendly front panel interface simplifies routine operation, programming, and setting adjustments.

  • Rated for 40-1200A up to 600V in 2, 3 or 4 pole configurations. Eaton's contactor based transfer switch is available in open, delayed, closed transition and non-automatic style.
  • UL1008 and CSA 22.22 No. 178-1978 listed.
  • The bypass isolation option provides industry leading Dual ATS technology, which allows both the ATS and the bypass switch to perform as automatic transfer switches.
  • The contactor transfer switch offering is available with the ATC-100 controller (40-100A open and delayed transition), the ATC-300 controller (40-1200A open and delayed transition), and the ATC-800 controller (40-1200A open, delayed and closed transition).
  • Specific and Any breaker ratings across entire contactor line provides the highest level of user flexibility in selecting the right transfer switch for your application.
  • Momentarily energized solenoid operating mechanisms offer a fast and reliable method of transfer.  The operating mechanism ie electrically and mechanically interlocked in open transition applications  to prevent inadvertent paralleling of source 1 and source 2.
  • All contactors 400A and below contain a stationary arcing contact and all contactors 600A and above contain a separate moveable "break first, make last" arcing contact.
  • Field-selectable multi-tap transformer panel permits operation on a wide range of system voltages.
  • Keyed quick-disconnect plugs are provided for easy and complete isolation of the control circuitry.
  • Programmable plant exerciser standard in all controller models.
