They have short circuit current ratings (SCCR) up to 100 kA with specified fuses and up to 65 kA with specified Square D™ circuit breakers in accordance with requirements set forth in national electrical code (NEC) and UL 508A. They are one-pole modular units with an interlocking dovetail feature that enables ganging of the blocks to create multi-pole configurations according to application requirements. NSYEB distribution blocks are either UL listed (UL 1953) for feeder circuits or UL recognized (UL 1059) for branch circuits and are CSA approved and RoHS compliant. CE marking ensures acceptance throughout the European community.
