GENERAL
Thomson TS873A0600B1AY6DNKAA ā 600 Amp Service Entrance Rated Automatic Transfer Switch, 3-Phase, Open Transition, NEMA 3R Enclosure
The Thomson TS870 Series 600 Amp Automatic Transfer Switch delivers dependable power switching performance for critical commercial and industrial operations. This UL 1008 service entrance rated ATS is engineered for high-reliability applications where consistent power availability is essential, such as in healthcare centers, data hubs, manufacturing facilities, and mission-critical infrastructure.
Designed for seamless utility-to-generator transfer, this model incorporates a 2-wire dry contact for automatic generator start, making it easy to interface with most standby generator systems. The switch uses a microprocessor-based TSC 7320 controller featuring a backlit LCD for real-time diagnostics, voltage monitoring, system frequency tracking, and advanced input/output programmability.
The TS873A0600B1AY6DNKAA is a 3-phase, 3-pole switch, supporting open transition (break-before-make) operation to safely disconnect from one source before connecting to anotherāprotecting against out-of-phase power transfer. This unit is fully rated for 600 amps continuous load, supports 120ā600V systems at 50/60 Hz, and includes a solid neutral connection for grounded 4-wire installations.
Housed in a durable NEMA 3R enclosure, this model is suited for both indoor and outdoor installations, offering protection from rain, sleet, and external debris. The integrated service disconnect eliminates the need for a separate upstream breaker on the utility feed, reducing overall equipment cost and installation complexity.
