Duty transfer switches in NEMA 4X enclosures

Russelectric announces its RTSCD commercial duty transfer switches are available in NEMA 4X enclosures for reliable outdoor operation and for resistance to corrosive environments. Educational campuses, high-rise complexes, industrial plants, and manufacturing facilities can rely on the RTSCD to provide emergency power needed to keep critical operations online. 

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

The RTSCD features a user-friendly operator interface panel with an intuitive keypad that features text and icons, and comes standard with a 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-centre mechanism results in the extremely quick switching operation. This 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 meets UL1008 up to 480 (VAC). It 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.
