B-LINE C25FNF375B – Frequently Asked Questions
1) Is the C25FNF375B a two-pole or three-pole contactor?
Three-pole, so it switches all three legs of a 3-phase load. It sits in the 60-75A frame, which B-Line builds in both two- and three-pole versions, but this specific model is the three-pole.
2) What amperage is the C25FNF375B definite purpose contactor rated for?
75A rating, with a resistive load rating of 90A per pole. The resistive figure applies to things like electric heat elements; sizing to a motor or compressor load should use the 75A number.
3) Can I land both quick-connect and screw terminals on this contactor?
Both. The C25FNF375B carries box lugs with posidrive setscrews plus side-by-side quick connect terminals, so line and load can be wired with lugged conductors while control leads push on. That matters on a rooftop unit retrofit where the existing harness is spade-terminated.
4) Does this contactor come in an enclosure or do I need to mount it in a panel?
It ships open with a metal mounting plate, no cover or box. Plan on installing it inside an existing equipment cabinet or a separately purchased enclosure. If the location is wet or outdoors and unprotected, you need an enclosed contactor instead.
5) How much space do I need inside the panel for the C25FNF375B?
The body measures 3.97 x 3.75 x 2.63 inches (length, height, width) and weighs 2.8 lb. Allow for conductor bend radius at the box lugs on top of that footprint when you lay out a crowded control cabinet.
6) Can I use this contactor to reverse a motor?
No. The C25FNF375B is a non-reversing contactor, single unit, no mechanical or electrical interlock. Reversing duty needs a reversing contactor pair with interlocking so two phases can be swapped without a cross-phase short.
7) Is a definite purpose contactor the right choice, or should I use a full motor starter?
A definite purpose contactor like the C25FNF375B switches power only, it has no overload relay. It suits HVAC compressors, condenser fans, electric heat and pumps where overload protection already lives in the equipment or upstream. If the load needs its own thermal overload, specify a motor starter or add a separate overload block.
8) What part number do I order to match an existing C25FNF375B?
Order by B-Line manufacturer part number C25FNF375B. Match the three-pole configuration and the 208-240 Vac coil when standardizing spares across a building so the same unit drops into any of your rooftop or heat panels.
