Product details

The 100 A rating means it protects a circuit carrying up to that continuous current — typically a motor or transformer primary — without nuisance tripping on inrush.

Compliance documentation

As an ABB S800S series MCB, the S803S-K100 is designed to meet IEC/EN 60898-1 and IEC/EN 60947-2 standards for overcurrent protection. RoHS and REACH compliance documentation is available from the manufacturer on request. The interrupting rating of 50 kA at 230 VAC is tested per IEC 60947-2.

Frequently asked questions

What is the closest functional second-source to S803S-K100?

The S203-D13 is a 3-pole, 10 A, Curve D MCB — not a direct second-source for the 100 A, Curve K S803S-K100. The S203-D13 has a 10 kA interrupting rating versus 50 kA, and its Curve D (10–20x In) is tuned for different inrush profiles. For a 100 A, Curve K requirement, the S803S-K100 is the correct part; no drop-in replacement exists without rewiring and re-coordinating the panel.

Where can I buy S803S-K100?

The S803S-K100 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation does ABB provide for S803S-K100?

ABB provides RoHS and REACH compliance declarations, plus IEC/EN 60898-1 and IEC/EN 60947-2 test certifications for the S800S series. The 50 kA interrupting rating at 230 VAC is verified per IEC 60947-2.
