Eaton/Cutler-Hammer FD3070L 3 Pole Circuit Breaker
The Eaton/Cutler-Hammer FD3070L is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 70 Amps and a voltage rating of 600VAC, 250VDC. It has an interrupting rating of 35kAIC at 480VAC, 65kAIC at 240VAC. The FD3070L has a feed-thru connection type and includes long time and instantaneous trip functions.
What is the difference between the FD3070 and the FD3070L?
The L suffix in the FD3070L catalog number indicates that the circuit breaker comes factory-equipped with line and load side lug terminals. The FD3070 is the base breaker without lugs.
Can I use the Eaton FD3070L to replace an older Westinghouse FD3070L?
Yes. Eaton acquired the Westinghouse distribution equipment business, and the Eaton or Cutler-Hammer Series C FD3070L is the direct, exact replacement for the legacy Westinghouse FD3070L circuit breaker.
Is the FD3070L suitable for reverse feed applications?
Yes. Eaton Series C F-frame thermal-magnetic circuit breakers without specific Line and Load markings are suitable for reverse feed installations.
How must the FD3070L be wired for 250VDC applications?
When used in direct current (DC) applications up to 250VDC, the poles of the circuit breaker must be wired in series to achieve the 10kAIC DC interrupting rating.
Does the FD3070L provide GFCI or AFCI protection?
No. The FD3070L is a standard thermal-magnetic circuit breaker with long-time and instantaneous (LI) trip functions. It does not provide ground fault (GFCI) or arc fault (AFCI) protection.
What types of enclosures and panels accept the FD3070L?
This F-frame breaker is designed for unit mount installations in Eaton Series C panelboards, switchboards, motor control centers, and dedicated F-frame enclosures.
