Eaton FAZ-C63 3-NA Molded Case Circuit Breaker

The Eaton FAZ-C63 3-NA is a miniature circuit breaker engineered to protect feeder circuits effectively against overload and short-circuit conditions within commercial and industrial power distribution environments. Constructed to handle a continuous current of 63 amps across three connected poles, this utility-grade unit isolates simultaneous faults in balanced 240-volt AC networks. By employing a Type C trip curve, the device tolerates moderate inrush currents associated with transformer loading or lighting ballasts without unnecessary interruption, providing distinct operational behavior compared to Type B or Type D alternatives suited for purely resistive or highly reactive motor loads.

Adherence to UL 489 standards verifies that the internal mechanisms satisfy rigorous safety protocols required for installation on power equipment including panelboards and motor control centers. The molded case construction ensures robust mechanical stability within standard switchgear arrangements, facilitating reliable mounting on compatible DIN rails alongside other protective devices. Precision matching of the designated amperage rating and pole configuration remains essential for electricians maintaining code compliance during complex electrical maintenance upgrades or new facility installations. Proper integration of this component prevents damage to downstream wiring insulation and connected load equipment caused by excessive thermal stress or magnetic flux during emergency fault events.
