B-Line Eaton Freedom motor control contactor, Freedom Series contactor, Non-reversing, 45A, 240V/60 Hz, 220V/50 Hz coil, Four-pole, -20° to 65°C o

It is rated 45A. That is the contactor's current rating across its four poles, so size it to the full-load current of the load you are switching plus any code-required margin. A motor drawing more than 45A at full load needs the next frame size up in the Freedom series.

No. This is a non-reversing contactor, a single power block with no mechanical interlock or second contactor. Reversing a three-phase motor needs two contactors interlocked so both cannot close at once, which is sold as a reversing assembly. Use the CN15GN4BB for straight across-the-line starting, pump and fan duty, lighting or heating loads.

It is a contactor only. There is no overload relay in the package, so on a motor branch circuit you still have to provide motor overload protection separately, plus short-circuit protection upstream. If you want overloads built in, order a Freedom starter rather than the bare contactor.

The manufacturer part number is CN15GN4BB: Freedom series, non-reversing, 45A, four-pole, 220-240 Vac 50/60 Hz coil, 65 mm frame. Match all four of those (amps, poles, coil voltage, frame) when replacing one in an existing panel, since the coil code is the item most often mis-ordered.

Four poles give you a fourth switched power pole, which is what you want when you have to break a neutral or a fourth phase conductor, switch four-wire heating or lighting banks, or open all conductors of a circuit rather than just the three phases. A standard three-phase motor only needs three poles; the four-pole CN15GN4BB is for the cases where the extra switched pole is part of the design.

Its operating temperature range runs from -20 to 65 degrees C, so it handles unheated mechanical rooms, rooftop enclosures and cold-climate winters at the low end and hot equipment rooms at the top. Below -20 C or above 65 C it is outside its stated range.

Plan for a device measuring 5.05 in height, 3.44 in width and 4.44 in length/depth, weighing 3.9 lb. The depth figure is what usually decides it, so check clearance from your back-pan to the enclosure door before you lay out the rest of the starter. The mounting frame is 65 mm.

The contactor is UL Listed. That is the listing an inspector looks for on a control component installed in a commercial or institutional panel, and it is what lets it be used in a UL-labeled assembly under the panel builder's own listing.
