An ATS for Every Project's Need
Automatic Transfer Switches (ATS) are an integral component in Caterpillar® Generator systems and are responsible for transferring power between utility and generator. Today every standby generator set that is sold can utilize at least one ATS, and in some cases multiple units.
Caterpillar offers one of the broadest ranges of transfer switch products in the marketplace and incorporates a solutions-based approach for CSA/UL/IEC listed applications. Cat ATS products offer differentiated features that simplify installation, operation, and system integration, yet are suitable for a wide array of environments from residential, industrial, commercial, and governmental to critical process and life-safety applications.
