Description
Engineered to support legacy electrical systems, the Eaton FB2020S is a 2-pole, 20A molded case circuit breaker. It operates across 600VAC and 250VDC networks, offering robust overcurrent defense for industrial facilities. This bolt-on unit serves as an exact substitute for the FDB2020, fitting seamlessly into existing Westinghouse switchboards. Facility managers can rely on its dimensions to maintain older enclosures. It delivers a 14 kAIC interrupting capacity at 480VAC with fixed LI trips.
