B-Line Eaton Freedom motor control contactor, Non-reversing, 45A, 600V/60 Hz, 550V/50 Hz coil, Four-pole, -20° to 65°C operating temperature, 65 mm

Plan for a footprint of 5 in by 4.44 in by 3.44 in and a unit weight of 3.9 lb. That weight matters if you're back-panel mounting on a light sub-panel or a DIN-rail adapter, since a 3.9 lb device needs solid support. Measure your available panel space against all three numbers before you commit, particularly depth behind the door.

The coil on the CN15GN4DB is a 550-600 Vac unit, 50/60 Hz, so it is driven at line-level control voltage, not 120 V. If your control circuit runs off a 120 V control transformer or a 24 V PLC output, this is the wrong coil code and you'll need a different suffix in the Freedom series. Confirm what your existing pilot devices and control transformer are putting out before ordering.

No. The CN15GN4DB is a non-reversing contactor, meaning it makes and breaks the motor circuit in one phase sequence only. To reverse a three-phase motor you need a reversing arrangement, which is two contactors mechanically and electrically interlocked so the phase rotation swaps. If the job calls for forward/reverse, order a reversing assembly rather than trying to interlock this one on your own.

The contact rating is 45A, so size it against the full-load amps on your motor nameplate, not the horsepower on the drawing. Note that a contactor is a switching device only. It carries no overload element, so you still need separate overload relays and short-circuit protection (fuses or a breaker) to make it a complete starter that protects the motor.

The CN15GN4DB is a four-pole device. A standard three-phase motor starter only needs three, so the fourth pole is there when you have to switch a neutral, a second control leg, or an additional load contact along with the motor phases. If you are switching a plain three-wire three-phase motor and nothing else, a three-pole contactor does the same job in a smaller footprint.

Yes, the CN15GN4DB carries a UL Listing. That is generally what an inspector or a spec-driven institutional job wants to see on a motor control component going into a panel.

Operating range on this Freedom contactor is -20 to 65 degrees C, which covers an unheated mechanical space, a rooftop unit enclosure in most climates, and a hot boiler room. At the cold end, check that your enclosure won't see sustained temperatures below -20 C; at the hot end, remember that the inside of a sealed NEMA 4 box in direct sun runs well above ambient.

Order Eaton part number CN15GN4DB. That designation ties together the 65 mm frame size, the four-pole non-reversing configuration, and the 550-600 Vac coil, so swapping any one of those means a different number. If you are replacing a failed unit in a panel, read the number off the side of the old device and match it character for character.
