B-LINE ED3225 – Frequently Asked Questions
1) Will the Eaton ED3225 breaker work on a 480V three-phase panel?
No. The ED3225 is rated 240 Vac, 125 Vdc only, so it cannot be applied at 480V. On a 480Y/277V or 480V system you need a breaker rated for that voltage class instead. It is a three-pole device, so it suits three-phase 240V or 208Y/120V systems within that rating.
2) Is the ED3225 a complete breaker or just a frame that needs a trip unit?
It ships as a complete molded case circuit breaker with line and load terminals included. The trip is fixed thermal, fixed magnetic, so there is no adjustable or interchangeable trip unit to order and nothing to field-set. You get one 225A three-pole device ready to install.
3) What frame size is the Eaton ED3225 and will it fit my existing ED-frame cutout?
It is an F-frame ED-type breaker in Eaton's Series C line. The body measures 4.13 in height, 3.38 in length and 4.13 in width, and it weighs 4.5 lb. If the panel or enclosure was built for a three-pole Series C ED breaker, the envelope matches; measure your existing cutout against those dimensions before you pull the old unit.
4) Can I adjust the trip setting on the ED3225 down from 225 amps?
No. The ED3225 uses a fixed thermal, fixed magnetic trip at 225A, so the setting cannot be dialed back. If your design calls for a lower continuous rating or an adjustable magnetic pickup for coordination, you need a different ampere rating or an electronic-trip breaker.
5) Can the ED3225 be used on a DC circuit?
Yes, up to 125 Vdc. The same breaker is rated 240 Vac for AC service and 50-60 Hz, so it covers both 50 Hz and 60 Hz AC systems as well as 125V DC applications.
6) What is the exact part number to order this 225A Eaton breaker?
The manufacturer part number is ED3225, an Eaton Series C three-pole 225A molded case breaker. The ED prefix is the breaker type, the 3 is the pole count and 225 is the ampere rating.
7) Will the ED3225 work as a main breaker on a 50 Hz system overseas?
Its frequency rating is 50-60 Hz, so 50 Hz service is within rating. The limit is voltage, not frequency: 240 Vac maximum. A 400/230V system exceeds the line-to-line rating of this breaker.
