question about 2 pole 120 arc fault breaker

[kylelee]

If I run a 14/3 wire by using 2 pole arc fault breaker for 2 dedicated circuits as the pic

, but it looks this two circuits must on/off together. However, I don't want two different circuits on/off together. Can I just take out the common trip. And is it designed for 240v arc fault or 2 120 circuit?

Even where afci's are not required, you can no longer have mwbcs without a handle tie. It was changed a few code cycles ago.

I believe the OP is in Canada.

Check out the "GFP in afci breakers" thread.

The "common trip" is done by the mechanism inside the body of the breaker and has nothing to do with the "handle tie."

The Code requirement for AFCI protection is only for 15 or 20 Amp 120 Volt. Now, a two-pole breaker is, ostensibly, a 240 / 120 Volt breaker, but I doubt the AFCI component is evaluated and listed for AFCI protection for 240 Volt loads.

I had no idea they even existed.

I believe so, and I read the instructions that it's designed for sharing neutral. Then the handle tie confusing me. Cause indeed I really don't need them on/off together

Do you have a multiwire branch circuit? If not use two single pole breakers. As mentioned "common trip" is internal, removing the handle tie will allow individual pole switching but when internals call for trip, both poles trip whether there is a handle tie or not.
