What this MCB does on the rail
Rated for 230 VAC, it interrupts faults up to 50 kA — enough headroom for high-fault panels downstream of a large transformer. Mounts on standard DIN rail, same as any 1-pole MCB in the panel.

Frequently asked questions
What is S801S-K16's interrupting rating?
50 kA at 230 VAC, which covers high-fault installations without needing a current-limiting upstream breaker.
What's the difference between S801S-K16 and S201MUC-K2?
The S201MUC-K2 is a 2 A, 1-pole Curve K MCB rated 6 kA interrupting at 277 VAC — so it's a lower-current, lower-fault-rated sibling. The S801S-K16 handles 16 A and 50 kA; physically both are 1-pole DIN-rail breakers, but the S801S-K16 belongs to the higher-fault S800S family. Panel wiring is the same, but the interrupting rating difference means they are not drop-in substitutes without verifying the fault current at the point of installation.
Where can I buy S801S-K16?
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 S801S-K16?
ABB typically provides RoHS and REACH declarations, plus IEC/EN 60898-1 and IEC/EN 60947-2 test certificates for the S800S series. Specific documentation is available with the order.
