The Eaton FDC3125 is a bolt-on molded-case circuit breaker (MCCB) rated 3-Pole, 125A, 600V AC, 35kA interrupting capacity. As an FD-frame MCCB, it is designed for installation in commercial and industrial panelboards and switchboards that accept Eaton FD-frame bolt-on breakers — not residential loadcentres. Typical applications include motor branch circuits, feeder protection, and distribution panels in manufacturing, commercial buildings, and utility rooms.
Panel fit depends on your specific switchboard or panelboard model. Send us your panel or switchboard model and we'll confirm compatibility.
The FDC3125 is rated 3-Pole, 125A, 600V AC with a 35kA symmetrical interrupting capacity at 600V. This means it can safely interrupt fault currents up to 35,000 amperes, making it suitable for commercial and industrial distribution systems where available fault current can be substantial. Always verify that the available short-circuit current at your installation point does not exceed this rating.
