Square D NF430L2C Panelboard Mounted Circuit Breaker

Square D NF430L2C NF Series panelboard interior delivers a 250 A, 3-phase, 4-wire distribution interior for 30 pole spaces, rated up to 600Y/347 VAC, with copper bus and an aluminum neutral assembly. This main-lug interior is designed to be installed inside NF panelboards to feed downstream circuits, and provides a flexible foundation for expansion; kits are available to replace standard main lugs with compression lugs, sub-feed lugs, or a vertically mounted main circuit breaker to convert to a main-breaker configuration. The enclosure footprint measures 10-7/16 in wide, 33 in high, and 5-3/4 in deep, and the assembly carries a 100 kA short-circuit current rating, suitable for demanding distribution applications. With 30 spaces, it accommodates a substantial number of branch circuits in a compact NF panelboard interior while maintaining copper bus and aluminum-neutral construction for reliable, low-impedance power distribution.
