Russelectric Launches Commercial Duty Transfer Switches in NEMA 4X Enclosures

Siemens power control systems business Russelectric has launched the RTSCD range of commercial duty transfer switches which are available in NEMA 4X enclosures for reliable outdoor operation and resistance to corrosive environments.

Applications for the switches include educational campuses, high-rise complexes, industrial plants, and manufacturing facilities that require emergency power to keep critical operations online.

Initial configurations include 100A, 200A, 260A and 400A rated models, with NEMA 4X enclosures available in either 304 grade stainless or 316 grade stainless. RTSCD is also available in UL Type 1 or Type 3R enclosures.

The solution features a user-friendly operator interface panel with an intuitive keypad that includes text and icons, and comes standard with an historical event log.

The product is available in 2, 3 and 4 pole models, with solid or fully rated switched neutral. Featuring rapid and reliable arc quenching, the front connected RTSCD offers manual transfer with rapid arc interruption, as well as a permanently affixed handle and double throw mechanically held contactor. Contacts are easily accessible for convenient inspection.

Preloaded springs and an electric operator-driven over-center mechanism results in extremely quick switching operation. This unique design instantaneously opens and closes the contacts, providing rapid full arc interruption, even under maximum voltage and amperage. This design considerably reduces contact erosion and effectively increases the switch’s useful life.

The RTSCD range meets UL1008 up to 480 (VAC) and complies with NFPA 110, NEC Articles 700, 701, 702, Enclosure UL Type 1 and IBC 2018 and CBC2019 seismic standards.

Optional accessories include a power monitoring package, auto/load test key switch and load shed relay, selector switch for auto/manual, pushbuttons for manual transfer, and a space heater/thermostat.
