Description
Built for commercial facilities, the Federal Pacific NE234045 is a 3-pole, 45A molded case circuit breaker utilizing fixed thermal-magnetic trip technology for LI protection. Designed as a direct replacement, it bolts into legacy FPE NE panelboards. This eliminates the need for complex retrofits, allowing facility managers to easily maintain older systems. It cross-references with UBINE234045 substitutes. Delivering an 18 kAIC rating at 240VAC, this breaker is suitable for reverse feed.Specifications
