Federal Pacific Electric NA3100 Circuit Breaker

Federal Pacific Electric NA3100 is a three-pole, 100-amp, 240-volt circuit breaker. It interrupts overcurrent to protect wiring and connected equipment by tripping when the current exceeds its rating. The three-pole design allows simultaneous interruption of all three conductors in a 240V circuit, which is important for protecting multi-wire or three-conductor configurations that share a neutral. With a 100A rating, this breaker is intended for circuits requiring robust protection for higher-load loads in 240V distribution networks. The NA3100 model designation identifies this specific Federal Pacific Electric device, reflecting its intended electrical characteristics and form factor within the brand’s line of 3-pole breakers. It serves to quickly disconnect power in the event of overload or short, helping to prevent damage and overheating in 240V distribution systems.
