Product details

Trip Curve K means the magnetic trip threshold is set between 8 and 12 times the rated current — 48 to 72 A for this 6 A unit. The 6 kA interrupting rating at 277 VAC covers most commercial lighting and small-panel fault levels; the 10 kA DC rating is useful for battery-backed or solar-string circuits up to 250 VDC.

DIN-rail integration

The 1-pole width (roughly 17.5 mm per module) means it occupies one slot in the panel — no special adapter or busbar needed for single-pole applications. Wire termination is via tunnel terminals; strip length and torque follow the manufacturer's installation guide for the S200MUC series.

Frequently asked questions

Will S201MUC-K6 drop into a panel that was specified around S201MUC-K2 without rewiring?

Yes — the S201MUC-K6 shares the same physical footprint, DIN-rail mount, 1-pole form factor, and terminal layout as the S201MUC-K2. The only difference is the amp rating (6 A vs 2 A) and the trip curve is identical (K). No rewiring or busbar change is needed; just swap the breaker.

What is S201MUC-K6's listed amps and trip curve?

The S201MUC-K6 is rated 6 A with a Trip Curve K characteristic, meaning the magnetic trip operates between 8 and 12 times the rated current — suitable for inductive loads.

Where can I buy S201MUC-K6?

The S201MUC-K6 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
