Eaton C25BNB220A – Frequently Asked Questions

1) What coil voltages does the Eaton C25 definite purpose contactor come in?
Three control voltages across the C25 range: 24V, 110-120V, and 208-240V, all 50/60 Hz. The coil voltage is baked into the part number suffix, so you order it, you don't change it later. Suffix T is 24V (C25BNB220T, C25DND230T, C25DNF240T), A is 110-120V (C25BNB220A, C25DND225A, C25DND230A, C25DNF240A), and B is 208-240V (C25BNB220B, C25DND225B, C25DND230B, C25DNF240B). Match the suffix to whatever your control transformer or thermostat circuit actually puts out.
2) What amp ratings are available on the Eaton C25 two-pole contactor?
The C25 two-pole non-reversing contactors run from 15A up through the 20-40A frame group, with resistive-per-pole ratings of 30A (C25BNB220 series), 35A (C25DND225), 40A (C25DND230), and 50A (C25DNF240). There is also a 15A option in 208-240V (C25DND215B) and 24V (C25DND215T) coil. Size off your equipment nameplate FLA, not off the breaker.
3) Can I use a two-pole definite purpose contactor to switch a three-phase compressor?
No. The C25 two-pole contactor switches two legs only, which covers single-phase motors, condensing units, heat strips, and general resistive loads. A three-phase compressor needs all three legs switched, so you want the three-pole version of the C25 frame instead. Eaton builds the C25 series in both two-pole and three-pole across the same amperage range, so the rest of your panel layout carries over.
4) What is the difference between the inductive full load rating and the resistive rating on a definite purpose contactor?
They are two different load types on the same contactor, and using the wrong one undersizes the part. On the C25, a unit rated 20A inductive full load carries 30A resistive per pole (C25BNB220 series); the 25A inductive unit is 35A resistive (C25DND225), the 30A is 40A resistive (C25DND230), and the 40A is 50A resistive (C25DNF240). Motors and compressors are inductive, so size against the lower number. Heat strips and other purely resistive loads use the higher one.
5) Does the Eaton C25 contactor take spade terminals or screw terminals?
Both, and you don't pick between them at order time. The C25 has screw/pressure plate terminals and quick connect (spade) terminals arranged side by side on the same terminal, so you can land a ring or stripped conductor under the screw and push a female quick-connect onto the tab for the control wiring. That is what makes it a straight swap in HVAC work where the factory harness is all spade connectors.
6) Is the Eaton C25 contactor a reversing contactor?
No, the C25 units here are non-reversing. They make and break a load in one direction only. If you need forward and reverse on a motor, a single non-reversing contactor won't do it, you need a reversing arrangement with two mechanically interlocked contactors.
7) I'm standardizing contactors across a portfolio of rooftop units. Can I stock one C25 part number for everything?
Usually not one, but you can get down to a short list. The two things that vary are the load rating and the coil voltage, and they're both fixed in the part number. Most commercial HVAC control circuits are 24V, so the 24V (T suffix) units cover a lot of ground: C25BNB220T at 30A resistive, C25DND230T at 40A, and C25DNF240T at 50A, plus C25DND215T at 15A. Stock by rating within the 24V group and the terminals, poles, and mounting stay identical across all of them, which keeps the install the same for whoever is on the roof.
8) Is the Eaton C25 contactor RoHS compliant for a government or institutional spec?
RoHS Compliant, yes. That is the compliance Eaton states on the C25 definite purpose contactor.
