Product details

On the AC side it interrupts up to 6 kA at 277 V; on DC it handles 10 kA at 250 V, which covers most control-circuit and small-load DC rails. Mounts on standard DIN rail, same footprint as any S200 series breaker.

The closest functional sibling is the S201MUC-K2, which shares the same 1-pole DIN-rail form factor, voltage ratings (277 V AC / 250 V DC), and interrupting capacities (6 kA AC / 10 kA DC). The difference is the trip curve and the amp rating: the K2 is a 2 A breaker with a Curve K characteristic (trips magnetically at 8–12× In), while the Z6 is 6 A with Curve Z (2–3× In). If your panel was specified around the K2 but the load draw is higher, the Z6 drops into the same slot without rewiring — same physical footprint, same terminal layout. The curve change matters: Z is faster on short-circuit, so verify the downstream equipment's inrush profile before swapping.

Frequently asked questions

Where can I buy S201MUC-Z6 and how do I get a price?

The part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

When sourcing S201MUC-Z6, what's the closest functional second-source — S201MUC-K2?

The S201MUC-K2 is the closest functional sibling: same 1-pole DIN-rail form factor, same AC/DC voltage ratings, same interrupting capacities. The differences are the trip curve (K vs Z) and amp rating (2 A vs 6 A).

What is S201MUC-Z6's listed amps (6) on this component line?

The rated current is 6 A. That's the continuous current the breaker carries without tripping under normal conditions.

What is S201MUC-Z6's listed type (Trip Curve Z) on this component line?

It's a Trip Curve Z characteristic, meaning the magnetic trip operates between 2 and 3 times rated current. That makes it suitable for protecting sensitive loads like semiconductors or long cable runs where high inrush isn't expected.

Will S201MUC-Z6 drop into a panel that was specified around S201MUC-K2 without rewiring?

Yes — same 1-pole DIN-rail footprint, same terminal layout, same voltage and interrupting ratings. No rewiring needed. Just verify the load's inrush profile against the faster Z curve.

What compliance documentation does this brand provide for S201MUC-Z6 (RoHS, REACH, UL, IEC)?

ABB typically provides RoHS and REACH declarations, plus UL and IEC certifications for the S200MUC series. Specific documentation is available on request with an RFQ.
