The ABB TMAX has an electric arc interruption system used on the Tmax circuit-breakers allows the short-circuit currents of very high value to be interrupted extremely rapidly. The considerable opening speed of the contacts, the dynamic blasting action carried out by the magnetic field and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time, notably limiting the value of the specific let-through energy and the current peak.
The dip switches on the S/I setting were skipped over in the video, I don't believe they stack like the L setting does?
Is the 50/100% neutral setting a % of the L dip switch setting or the breaker maximum or 50/100% of something else?
Hi I have a TMAX T3C 250 that needs to be replaced, I checked there is no old model, what is the replacement for it because I checked the old model and there is no one available
Thanks for sharing i have same abb breaker its working normally but after shutdown its not working what is the issue ???
You fu*ked it up.
what is mean + and - Test
@GALCOTV Do we need to set the MCCB to TEST position before changing the DIP Switch position and setting ?
Did you READ the manual or searching for an easy answer. ???
How about explaining the multipliers for the Long Time and the short time. You skipped over that bit. Thanks
What is the LUG TEMPERATURE RATINGS of IEC BREAKERS?

Have a problem in tmax the 1250

Sir I have a 630 Amp ABB sace Tmax mccb, it's getting trip during starting of motor, as motor is connected to fan load it take 936amps current for 50 seconds and then back to nominal current, Plz help for trip time characteristics
I need to set up the ABB circuit breaker RC222 please
Ok Khalled, the only thing I could find for you is the RC223 trip mechanism that attaches to a Tmax series CB. However the RC222 portion of this is in this manual written in 5 different languages, so just click this link library.e.abb.com/public/cec8ab4eccce1cc0c12578080070eca9/1SDH000471R0001.pdf and you should be all set.
This video explain nothing, sorry.

You may have to increase your "Starting Class" parameter. Class 10 is minimum, you should also have class 20 and 30 selections which are for longer starting times at very heavy loads during starting. So try increasing this parameter/adjustment. Great question, good luck.
