Eaton PDG23M0125TFFL 125A 3-Pole 600V Molded Case Circuit Breaker | Power Defense Feed-Thru

Eaton PDG23M0125TFFL – Power Defense Molded Case Circuit Breaker

The Eaton PDG23M0125TFFL is a globally rated, Frame 2, three-pole thermal-magnetic molded case circuit breaker (MCCB) engineered for reliable overcurrent and short-circuit protection in demanding commercial and industrial power distribution systems. Rated at 125 Amps and 600VAC, this Power Defense breaker delivers a high interrupting capacity of 65kA at 480V, making it one of the most capable breakers in its class.

Designed for standard load-only (feed-thru) terminal configurations, the PDG23M0125TFFL features a fixed thermal-magnetic trip unit (Fxd-Fxd) for consistent, predictable overload and short-circuit response — no adjustments required.
