Notes:

1) All WCR values indicated are tested in accordance with the requirements of UL 1008. See ASCO Pub 1128 for more WCR information.
2) Application requirements may permit higher WCR for certain sizez of switches. Contact ASCO for guidance if application requires higher WCR.
3) Based on 3 cycles for 260-4000A and 1.5 cycles for 30-230A switches. Applicable to circuit breakers with instaneous trip elements.
4) Short Time ratings are provided for applications involving circuit breakers that utilize trip delay settings for system selective coordination.
5) Optional front connected service(Accy 40MY and 40NY) limits 1600 and 2000A G Frame switches to 85kA Any Breaker rating.
6) J Frame switches utilizing overlapping neutral(code "C") are limited to 35kA Any Breaker rating at 480V.
7) 7000 Series Bypass Switches ONLY.
