Russelectric RS-ATS-1000A Automatic Transfer Switch

The Russelectric RS-ATS-1000A Automatic Transfer Switch is a 1000-amp, three‑phase, four‑pole device designed to automatically transfer a load between two power sources in 480V systems with 277V line-to-neutral. Built for applications where power continuity matters, the RS-ATS-1000A supports straightforward integration in commercial or industrial electrical installations that require reliable source selection as utility conditions change. The four‑pole configuration ensures full isolation of all three phases during a transfer, helping to protect connected equipment and maintain service when a source becomes unavailable. As part of Russelectric's ATS family, this model reflects the brand's focus on automatic transfer capability and dependable operation in 480V environments, and aligns with the broader Siemens portfolio of power-switching solutions. The RS-ATS-1000A is designed to operate with standard control wiring and sources such as utility feeds or standby power sources, enabling automatic switching without manual intervention. In practice, this unit is used to automatically switch loads off a failing or unstable source and onto a healthy alternate source, reducing interruption to circuits connected to the switch and providing a clear path for safe transfer between sources.
