B-LINE CN55GN3EB – Frequently Asked Questions
1) What coil voltage does the Eaton Freedom CN55GN3EB contactor use?
The CN55GN3EB reversing contactor uses a 480V/60 Hz coil, also rated 440V/50 Hz. If your control circuit runs 120V or 240V, this is the wrong coil and you need a different suffix in the Freedom line. Coil voltage is the first thing to confirm, because the power poles and the coil are separate circuits and a mismatch will burn the coil.
2) How many amps is the CN55GN3EB contactor rated for?
45 amps, across three poles. That continuous rating is what you size against the motor full load current and the overload relay, not the horsepower on the nameplate alone.
3) Is the CN55GN3EB a reversing contactor or a single starter?
It's a reversing unit, meaning two mechanically and electrically interlocked three-pole contactors that swap two of the three phases to run a motor forward or reverse. If you only need one direction, a non-reversing Freedom contactor of the same 45A rating is the simpler and smaller choice.
4) Will the CN55GN3EB fit inside my existing control enclosure?
The unit measures 5.05 in high, 2.56 in wide and 4.44 in deep, and weighs 3.1 lb. Check the depth against your enclosure and allow wire bending room at the line and load terminals before you commit to a panel layout.
5) Is this Eaton Freedom contactor UL Listed for a commercial panel?
Yes, the CN55GN3EB carries a UL Listing. For an institutional or MRO spec that calls for listed motor control components, that is the rating on record for this part.
6) Can I use the CN55GN3EB to start a single phase motor?
It's built as a three-pole device for three phase motors. You can wire two poles to a single phase load, but a reversing three-pole assembly is more hardware than a single phase job needs, and reversing a single phase motor requires switching the start winding rather than swapping line phases. For single phase, look at a two-pole contactor instead.
7) Does the CN55GN3EB come with overload protection built in?
This is a contactor, the switching half of a motor starter. Overload protection is a separate relay that mounts to it, and short circuit protection is your breaker or fuses upstream. Order the overload sized to the motor's full load amps within the 45A frame.
8) What exact part number do I order for this Eaton Freedom reversing contactor?
Eaton catalog number CN55GN3EB. That designation fixes the 45A rating, the three-pole reversing configuration, and the 480V 60 Hz coil together, so quoting it is enough for a distributor to pull the right unit.
