Product details

It handles 277 VAC and interrupts faults up to 6 kA — enough for most branch circuits in a 480Y/277 V panel, but check your available fault current before committing the BOM line.

The 2 A rating governs the continuous load the breaker can carry — sized for a small lighting circuit or a control transformer, not a motor branch.

Single-pole width saves space in a crowded enclosure — leaves room for additional breakers or contactors in the same row. The thermal-magnetic trip mechanism is self-contained; no external power required for operation.

Frequently asked questions

Where can I buy S201-C2 and how do I get a price?

The S201-C2 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 price and lead time.

What is S201-C2's listed amps (2) on this component line?

The S201-C2 is rated 2 A continuous current. That's the maximum load the breaker can carry without tripping under normal conditions.

What is S201-C2's listed type (Trip Curve C) on this component line?

Trip Curve C means the magnetic trip activates between 5 and 10 times rated current — 10 to 20 A for this 2 A breaker. It's suited for moderate inrush loads like small transformers or capacitor banks.

Will S201-C2 drop into a panel that was specified around S201M-C3 without rewiring?

The S201-C2 and S201M-C3 share the same 1-pole DIN rail footprint and voltage rating (277 VAC), so mechanical fit is the same. But the S201M-C3 is rated 3 A with a 10 kA interrupting at 60 VDC; the S201-C2 is 2 A, 6 kA AC only. If the panel was designed for 3 A continuous load or requires DC interruption, the S201-C2 won't substitute without a circuit redesign.
