Overview
Cat® Service Entrance Rated (SER) automatic transfer switches (ATS) are designed to provide standby power emergency power to entire installation loads to protect against utility power interruption; yet allow the ATS to be as close as possible to the point of service entrance. By safely and in code compliance, integrating the necessary overcurrent protection and service disconnecting means into the automatic transfer switch, a single installation can be made at the service entrance. This design eliminates the need for a separate upstream fault protection and respective interconnections, which in turn reduces installation space, time, and cost. Breaker-based Service Entrance Rated transfer switches are available from 30A to 5000A.
