B-LINE CN15GN4CB – Frequently Asked Questions
1) What coil voltage does the Eaton Freedom CN15GN4CB contactor use?
The CN15GN4CB takes a 440-480 Vac coil, 50/60 Hz (480V at 60 Hz, 440V at 50 Hz). If your control circuit runs 120V or 240V, this is the wrong coil code and the contactor will not pull in.
2) Can I use this Freedom Series contactor to reverse a motor?
No. The CN15GN4CB is a non-reversing contactor, a single power block with no mechanical interlock or second contactor. For forward/reverse duty you need a reversing contactor or two interlocked units.
3) How many poles does the CN15GN4CB have, and can it switch a three-phase motor?
It is a four-pole device, so it will switch a three-phase load and leave a fourth pole for a neutral, a second circuit, or an auxiliary switching function. Three-phase motor control is exactly what the Freedom NEMA line is built for.
4) What current is this Eaton Freedom contactor rated for?
45 amps. Size your motor full-load amps under that figure and allow for service factor and starting duty before you commit to this frame.
5) What exact part number should I order to match an existing Eaton Freedom 45A four-pole contactor?
Order Eaton Freedom Series part number CN15GN4CB. Match the full code, not just the amp rating, since the trailing characters set the coil voltage (440-480 Vac) and pole count on this family.
6) Will this contactor hold up in an unheated mechanical room or a hot rooftop enclosure?
Operating temperature runs -20 to 65 degrees C, which covers unheated winter spaces and hot rooftop or boiler room panels. Enclosure rise still counts against that ceiling, so allow for internal panel temperature, not just ambient outside the box.
7) How much panel space do I need for the CN15GN4CB?
Plan for a 5.05 in height, 3.44 in width and 4.44 in depth, and it weighs 3.9 lb. On a 65 mm frame size, budget wiring bend space and gutter clearance on top of those figures when laying out a backplane.
8) Is the Eaton Freedom CN15GN4CB UL Listed for use in a control panel?
Yes, it carries a UL Listed mark, which is what most AHJs and institutional specs want to see on motor control components inside a listed panel.
9) Is this contactor a complete motor starter with overload protection?
No. The CN15GN4CB is the contactor alone, a non-reversing switching block. Overload relay, enclosure and short-circuit protection are separate items, so spec those to your motor and branch circuit to make a complete starter.
