ATC Molded Case Circuit Breaker & Molded Case Switch ATS
Cat® transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability and value in a compact package. The open transition breaker-based Automatic Transfer Switch (ATS) will provide fully functioning transfer in applications where a momentary loss of power is acceptable on retransfer from emergency to normal power supply. The Cat Open Transition MCCB & MCS types of ATS also permits periodic testing of the emergency source without interrupting power to the loads and are available from 30 to 1000 amperes.
