Eaton / Cutler-Hammer DA3400 – 400A 3 Pole Molded Case Circuit Breaker Limited Time

Operating as a high-capacity protective device, the Eaton DA3400 delivers 400A of thermal-magnetic protection for demanding industrial environments. This 3-pole legacy AB De-Ion breaker features a non-interchangeable trip unit and supports reverse feed applications. It mounts securely into vintage Westinghouse CDP panelboards, FDP switchboards, and Eaton enclosures. Facilities looking to modernize often cross-reference this unit to the newer DK3400 replacement.
