Description
Maintaining legacy commercial electrical infrastructure requires specific hardware like this 40-amp molded case unit. It provides essential long-time and instantaneous trip functions for standard branch circuits. Designed to fit NBLP, NBC, NBDP, and CDP panelboards, the device fastens securely via bolt-on connections. Facility managers can use it to substitute the UBIF240NB without modifying existing enclosures.
