DC Main Panel Helm C Breaker, 1999 3500 Express

[NIVEK]

My Helm C breaker on the DC main panel in the engine room of 1999 3500 Express seems to have failed. Does anyone know the exact replacement breaker and amps? Are Helm A and B the same? I have contacted Tiara but wanted to check here as well. Would like to have part for next visit to boat rather than removing old to ID then ordering.
Thanks for your help.

Not sure about the amp rating, should be stamped on the old breaker. you can use pretty much any brand breaker for replacement ( Blue Sea, marinco, etc).
