RDT Transfer Switch Spec Sheet

G11-139 (Model RDT Automatic Transfer Switch) 3/20f Page 3
Contactor Ratings with Coordinated Circuit Breakers
The transfer switches are UL listed at 240 VAC maximum. The following table lists contactor withstand current ratings (WCR) for
100- 400 ampere non-service entrance rated switches with specific manufacturer’s circuit breakers per UL and Canadian safety
standards. Suitable for control of motors, electric discharge lamps, tungsten filament lamps and electric heating equipment where
the sum of motor full-load ampere ratings and the ampere ratings of other loads do not exceed the ampere rating of the switch and
the tungsten load does not exceed 30 percent of switch rating.
