The Federal Pacific NEF431050 is a 50 A, three-pole circuit breaker designed for 480 V three-phase electrical systems. It employs a thermal-magnetic trip mechanism to provide overload protection with an instantaneous magnetic trip during short circuits. With a 14 kA interrupting capacity, this breaker protects feeders and branch circuits from fault currents up to 14 kiloamps in a 480 V service, making it suitable for applications where 50 A protection and 480 V service are required.
