Overview
200A Automatic Transfer Switch (ATC3C2X20200WSU)
These automatic transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability, and value in a compact package. The open and delayed transition contactor-based ATS provides fully functioning transfer in applications where a momentary loss of power is acceptable during transfer and retransfers between normal and emergency power supply. The closed transition contactor-based ATS is designed to meet application requirements where emergency backup power is required with no momentary loss of power by connecting both sources before the transfer occurs. Closed transition also permits periodic testing of the emergency power source without interrupting power to the loads.

| Contact Composition | |
| Caterpillar utilizes silver composition contacts designed to meet the stringent requirement of UL 1008. All contactors are designed so that the contacts can be visually inspected without major disassembly and are protected by arcing contacts. | |
| Controls and Wiring | |
| All control relays and industrial-grade relays are totally encapsulated to minimize exposure to dust and dirt. Lugs are 90 degrees Celsius rated and all control wire is #16 AWG, type XLPE with a 125 degrees Celsius temperature rating. | |
| Enclosure | |
| The ATS is housed in rugged steel NEMA 1 (for indoor) or NEMA 3R (for outdoor) enclosure, which is Seismic Zone 4 Qualified (BOCA, CBC, IBC, UBC). ATS enclosures have three door hinges to ensure proper support of the door and door mounted devices. The hinges have removable hinge pins to facilitate door removal for easy wall mounting or service and are supplied with pad-lockable latches. | |
