Eaton C25BNB240B – Frequently Asked Questions

1) Will an Eaton C25BNB240B definite purpose contactor work with a 240V control circuit?
Yes. The C25BNB240B coil is rated 208-240 Vac, 50/60 Hz, so it drops straight onto a standard commercial 208V or 240V control voltage. If your thermostat or control transformer puts out 24V, this is the wrong coil and you need a 24V-coil version instead.
2) Is a 40A definite purpose contactor enough for my condenser or compressor motor?
The 40A figure is the inductive full load rating, which is the number that applies to motor, compressor, and pump loads. For resistive loads such as heat strips or incandescent lighting it carries 50A. Size against the inductive rating for anything with a motor in it.
3) How much panel space does the Eaton two-pole definite purpose contactor take up?
The two-pole frame measures 1.97 in wide, 2.32 in deep, and 3.19 in high. It ships open type on a metal mounting plate, so plan on mounting it inside an existing panel or enclosure rather than on an open wall.
4) Can I use spade terminals, or do I have to land ring lugs on this contactor?
Both work. The terminals are binding head screw plus quick-connect, arranged side by side, so you can push on a spade quick-connect for control wiring and screw down line and load conductors on the same device.
5) Can this Eaton contactor be used to reverse a motor?
No. It is a non-reversing two-pole contactor, built for single-direction load control. Reversing a three-phase motor takes a pair of mechanically interlocked contactors or a reversing starter, not this device.
6) Is the Eaton definite purpose contactor CSA certified and RoHS compliant for a spec job?
Yes on both. The contactor is CSA Certified and RoHS Compliant, which covers the two items most commonly called out on commercial and institutional control panel submittals.
7) What is the difference between the 40A and 300A Eaton definite purpose contactors?
Two amperage builds are offered: the 40A C25BNB240B compact two-pole unit, and the larger 300A C25FNF375C. Pick by the full load current of the equipment being switched; the 40A frame is the one sized for typical rooftop units, condensers, and small pump circuits.
8) Will a two-pole contactor switch a three-phase motor?
Not properly. Two poles break two legs only, so a three-phase load needs a three-pole device. Use this two-pole unit for single-phase motor, compressor, pump, heating, or lighting loads where breaking two legs is what the circuit calls for.
