The Westinghouse/Westinghouse FDB3050L molded-case circuit breaker with the 1494D-N4 on/off disconnect provides 50 A, 3-pole, thermal-magnetic overcurrent protection in a single disconnect-enabled assembly. Designed for panel or enclosure mounting, it offers manual ON/OFF disconnect control and is intended for branch-circuit protection and equipment isolation in MCCs, switchgear, and industrial control panels operating at 50/60 Hz. Part of the FDB frame family, this combination of FDB3050L breaker and Westinghouse 1494D-N4 switch is listed for common replacements such as Eaton FDB3050L, Westinghouse 1494F Disconnect Switch, and Square D FA3450.
