Eaton’s contactor type automatic transfer switches (ATS) are designed to quickly and reliably transition critical loads between preferred and alternate/generator power sources. Ideal for use in NFPA 70 emergency, legally required, optional standby, and critical operations systems that demand reliable performance.
Intelligent controllers can help you make informed decisions and perform efficient maintenance related to your automatic transfer switch (ATS) activity
Eaton offers controller models that allow for remote management, advanced diagnostics, programmable setpoints, integral metering and innovative features such as ATS Health and Maintenance Watch™ - available with the ATC-900
Eaton’s contactor type transfer switches can be equipped with an integrated Cam-Lok receptacle power panel that serves as a docking station for quick connection of a portable or temporary generator to supply critical electrical loads with emergency power during a utility outage.
Reliable, rugged, versatile and compact assemblies for transferring essential loads and electrical distribution systems from one power source to another.
