Overview

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.

Equipment

Standard Equipment

Controls and Wiring

All controls relays and industrial grade relays are totally encapsulated to minimize exposure to dust and dirt. Lugs are 90º rated and all control wire is #16 AWG, type XLPE with a 125º temperature rating.

Enclosure

Durable powder-coated steel NEMA 1, NEMA 3R and NEMA 12 are available with ATC-100 and ATC-300+ controllers. NEMA 4 is only available with the ATC-800 controller. The enclosures are Seismic Qualified (BOCA, CBC, IBC, UBC). The hinges have removable hinge pins to facilitate door removal for easy wall mounting or service and are supplied with pad-lockable latches.
