Eaton FD3125 is a three-pole molded-case circuit breaker rated for 125 A at up to 600 VAC. As a three-pole unit, it provides overcurrent protection for three-phase power systems by interrupting all three phases on overload or fault. The FD3125 designation communicates its 3P configuration, 125 A current rating, and 600 VAC operating voltage. Manufactured by Eaton, this MCCB is designed for use in industrial and commercial electrical distributions requiring reliable three-phase protection in standard MCCB enclosures. Use with compatible Eaton panels and termination methods to ensure proper fit and function.
