Product details

Interrupt rating is 50 kA at 240/415 V AC — that's a serious short-circuit capacity for a 1-pole device. For a panel engineer coordinating selectivity, that figure gives headroom downstream of a larger main breaker. The dual tripping mechanism (thermal for overload, electromechanical for short circuit) is standard for MCBs, but the K-curve's magnetic trip point is typically 10–14× rated current, so it holds through motor start without dropping out.

The S801S-K10 complies with IEC/EN 60898-1 and IEC/EN 60947-2, covering both residential and industrial applications. Compliance documentation (RoHS, REACH) is available from the manufacturer; UL/CSA listings are typical for this series but should be verified against the specific project jurisdiction.

Frequently asked questions

Where can I buy S801S-K10 and how do I get a price?

The S801S-K10 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

When sourcing S801S-K10, what's the closest functional second-source — S201MUC-K2?

The ABB S201MUC-K2 is a 1-pole K-curve MCB but rated at 2 A with a 6 kA interrupting capacity at 277 V AC — significantly lower fault rating and a different current class. It will not drop into a panel specified around the S801S-K10 without recalculating the short-circuit protection and load current.

What is S801S-K10's listed amps (10) on this component line?

The S801S-K10 is rated at 10 A continuous current.

What is S801S-K10's listed type (Trip Curve K) on this component line?

The S801S-K10 is a Trip Curve K MCB — the magnetic trip threshold is set higher than B or C curves, suitable for loads with moderate inrush current.

Will S801S-K10 drop into a panel that was specified around S201MUC-K2 without rewiring?

No — the S201MUC-K2 is a 2 A device with a 6 kA interrupt rating, while the S801S-K10 is 10 A with 50 kA. The physical footprint (1-pole DIN) is the same, but the protection settings and fault capacity are different; rewiring and coordination study are required.

What compliance documentation does this brand provide for S801S-K10 (RoHS, REACH, UL, IEC)?

The S801S-K10 complies with IEC/EN 60898-1 and IEC/EN 60947-2. RoHS and REACH declarations are available from ABB. UL/CSA listings are typical for the S801 series but should be confirmed per project jurisdiction.
