Description
Supplying 25 amps of thermal-magnetic protection, this legacy E-Frame component is essential for maintaining older commercial power systems. It operates safely across a wide voltage range, including 600VAC and 250VDC applications. Engineers utilize this exact-fit solution for aging ITE FC, FCI, and CDP panelboards. It eliminates the need for complex retrofits and serves as a substitute for the ED62B025. With an 18kAIC rating at 240V, it ensures dependable fault clearing for legacy switchgear.Specifications
