Eaton C25FNF250B – Frequently Asked Questions

1) What coil voltages does the Eaton C25FNF definite purpose contactor come in?
Coil voltage is an ordering choice on the Eaton C25FNF contactor: 110/120 volts, 208/240 volts, and 440/480 volts. The coil is what your thermostat or control circuit energizes, so match it to your control transformer secondary, not to the motor supply. Example part numbers: C25FNF250B and C25FNF350A are 110/120 volt coils, C25FNF275B is a 208/240 volt coil, and C25FNF360C is a 440/480 volt coil.
2) What amperage ratings are available on the Eaton C25FNF, and what does the frame rating mean?
The family covers frame sizes 15 to 50 A in two- and three-pole builds, with the amp figure given as a resistive load rating per pole. Orderable amperage options run 50, 60, and 75 amperes, for example C25FNF350A at 50 amperes and C25FNF275A at 75 amperes. Size against the resistive per-pole rating for your load, not against a combined panel total.
3) Can I use a definite purpose contactor like the Eaton C25FNF to reverse a motor?
No. The C25FNF is a non-reversing contactor, so it switches a load in one direction only. Reversing a three-phase motor requires two mechanically interlocked contactors or a reversing contactor assembly that swaps two line phases. Use this one for single-direction motor duty, compressors, fans, and general load switching.
4) How do I wire an Eaton C25FNF contactor, and does it take spade terminals or screw lugs?
Both. The C25FNF carries box lugs with posidrive setscrews plus side-by-side quick connect terminals, so you can land stranded conductors under the lug or push on a spade connector for coil and control leads. That is useful on HVAC changeouts where the existing harness is already terminated with quick connects.
5) Is the Eaton C25FNF contactor rated for a 277 volt lighting circuit?
Yes. The contactor is rated 277 Vac at 60 Hz, which covers 277 volt lighting branch switching as well as definite purpose motor and equipment loads. Remember the coil voltage is separate from that load rating, so a 277 volt lighting job still needs a control circuit matched to whichever coil you order.
6) Two-pole or three-pole contactor, which one do I need?
The C25FNF is built both ways. Two-pole is the usual choice for single-phase HVAC compressor and condenser fan duty where only the ungrounded conductors are switched. Three-pole is what you want on three-phase motors so all three lines break together. The amperage and coil voltage choice is independent of pole count, so decide poles from the supply first.
7) Is the Eaton C25FNF contactor RoHS compliant for our restricted-substance spec?
It is. RoHS compliance is stated for the C25FNF definite purpose contactor, which is what most institutional and OEM purchasing specs are looking for on restricted substances.
