Eaton ED3225 – Frequently Asked Questions
1) Is the Eaton ED3225 breaker a complete breaker or just a frame that needs a trip unit?
ED3225 ships as a complete molded case breaker, not a frame requiring a separate trip unit. Its trip is fixed thermal, fixed magnetic, so there is nothing to select or set, and line and load terminals come with it.
2) Can I use the ED3225 on a 480V three-phase panel?
No. The ED3225 is rated 240 Vac and 125 Vdc only, so a 480Y/277V or 480V delta system is out of range. For a 480V application you need a breaker rated to that voltage, not this one.
3) What interrupting capacity does the Eaton ED3225 give me at 240V?
65 kAIC at 240 Vac. That covers most commercial services where the available fault current at the panel is calculated at or below 65 kA. If your short circuit study comes back higher at that point in the system, this breaker is not adequately rated.
4) What frame size is the Eaton ED3225, and will it drop into an existing ED-type space?
It is an Eaton Series C F-frame breaker of the ED type. If the panel or switchboard interior was built for a three-pole F-frame ED breaker, that is the same family. The body measures 4.13 x 3.38 x 4.13 inches, so you can check it against the space you have.
5) Is the ED3225 a three-pole breaker for three-phase loads?
Three-pole, 225A, rated 240 Vac. That suits a three-phase 208V or 240V feeder, a large RTU, or a subpanel main. For single-phase 240V service you would be paying for a pole you do not use.
6) Can the Eaton ED3225 be used on a 125 VDC circuit?
Yes. Along with 240 Vac it carries a 125 Vdc rating, which covers DC control, battery, and UPS distribution at that level. The 65 kAIC figure applies at 240 Vac.
7) Can the trip setting on the ED3225 be adjusted in the field?
No. The ED3225 uses a fixed thermal, fixed magnetic trip unit, so both the overload and the instantaneous pickup are factory set at 225A. If your coordination study calls for an adjustable instantaneous or an electronic trip, you need a different breaker type.
8) Will the ED3225 work on 50 Hz power for imported equipment?
Yes, it is rated 50-60 Hz, so a 50 Hz system or 50 Hz imported machinery is fine as long as the voltage stays within 240 Vac.
