The 6 A rating at 30 °C is the headline number, but the derating curve matters in a warm panel: at 40 °C the continuous current drops to 0.93 A, and at 45 °C it recovers to 5.4 A. That 0.93 A figure at 40 °C looks like a data anomaly — likely a typo for 5.93 A given the pattern — but the takeaway is that this breaker is thermally sensitive and should not be loaded to its full 6 A in a crowded enclosure above 30 °C.

Frequently asked questions
Will the 5SL6106-6YA drop into a panel specified around the 5SL6120-7?
Yes, mechanically it is a direct drop-in replacement — same 18 mm width, 76 mm depth, 90 mm height, same DIN-rail mounting and any-position orientation. The only difference is the tripping characteristic: B curve on the 5SL6106-6YA versus C curve on the 5SL6120-7. If the panel design and upstream coordination were built around a C-curve let-through, swapping to a B curve may cause nuisance tripping on mild overloads or may not coordinate with the upstream device. Verify the coordination study before substituting.
