RTSCD Commercial Duty Transfer Switch


RTSCD commercial duty transfer switch provides emergency power needed to keep critical operations online. Available in 100, 200, 260, and 400A rated models, the switch 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-center mechanism results in an 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 meets UL1008 up to 480V AC. 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.
