Eaton/Cutler-Hammer FD3200L Circuit Breaker

The FD3200L is a Series C F-frame breaker designed for use in Eaton, Cutler-Hammer, and Westinghouse panelboards, switchboards, and enclosures. It is commonly installed in Pow-R-Line 3a (PRL3a) and Pow-R-Line 4 (PRL4) distribution panels.

Yes, the L suffix in the FD3200L catalog number indicates that standard line and load lugs are included. These factory-installed terminals accept 4 AWG to 4/0 AWG copper or aluminum conductors.

These prefixes indicate the interrupting capacity of the Series C F-frame breakers at 480VAC. The FD3200L is the standard tier rated at 35kAIC. The HFD is the high-interrupting version rated at 65kAIC, and the FDC is the current-limiting version rated at 100kAIC. All three share the same physical footprint.

Yes. Eaton manufactures the Series C line, which was formerly branded under Cutler-Hammer and Westinghouse. A new Eaton FD3200L is an exact drop-in replacement for legacy Westinghouse or Cutler-Hammer breakers with the same catalog number.

While the FD3200L supports internal accessories such as shunt trips, auxiliary contacts, and undervoltage releases, Eaton requires these to be factory-installed. Field installation of internal accessories in Series C F-frame breakers voids the UL listing.

Yes, this thermal-magnetic breaker is suitable for reverse feed applications. It does not have restrictive line and load markings, allowing power to be supplied from either the top or bottom terminals.

No, the FD3200L features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory set and cannot be adjusted in the field.
