Frequently asked questions

Where can I buy S273-K10 and how do I get a price?

The S273-K10 is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm availability and current pricing.

What is the closest functional second-source to S273-K10?

The closest functional second-source within the same S270 series is the S273-K4A (4 A K-curve) or S273-K6A (6 A K-curve). Both share the same DIN-rail footprint, weight, and K-trip characteristic — the only difference is the rated current. The S273-K10 will drop into a panel specified around the S273-K4A without rewiring, provided the load current is within the breaker's rating.

Will S273-K10 drop into a panel that was specified around S273-K4A without rewiring?

Yes, the S273-K10 shares the same DIN-rail footprint, single-pole modular width, and K-trip characteristic as the S273-K4A. No rewiring is needed if the branch circuit load current is within the 10 A rating.

What compliance documentation does ABB provide for S273-K10?

The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code. Standard ABB miniature circuit breakers in the S270 series typically carry CE and UL certifications, but confirm with the supplier at quote time.
