The ABB S273-K6NA is a 6A miniature circuit breaker from the S273 series, designed for DIN rail mounting in distribution panels and control cabinets. Rated at 6A, it protects branch circuits against overload and short-circuit conditions in commercial and light industrial installations.
Yes, both the S273-K6NA and S273-K40A share the same S273 series DIN rail footprint and 0.45 kg weight, so mechanical fit is identical; however, the 6A vs 40A current rating means the breaker must match the protected circuit's design.
