Withstand and Close-On Ratings (WCR)
Service Entrance Transfer Switch Ratings
The service entrance transfer switch is factory-equipped with a normal source disconnect circuit breaker .
Suitable for the 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.
Switch Rating, Amps * WCR, RMS Symmetrical Amps at 240 VAC
100, 150, 200 22,000
300, 400 35,000
* Continuous load current not to exceed 80% of switch rating.
Contactor Ratings with Coordinated Circuit Breakers
Single-phase transfer switches are UL listed at 240 VAC maximum. Three-phase transfer switches are rated at 480 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 the 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.
The transfer switch is rated for use on a circuit capable of delivering not more than the RMS symmetrical amperes maximum as
shown in the tables below, but no greater than the interrupting capacity of the selected breaker.
