It interrupts faults up to 10 kA, so it clears short circuits up to that level without needing an upstream device to trip first — that's the SCCR headroom for a branch circuit in a 480Y/277 V panel. Trip Curve C means it holds through inrush up to 5–10× rated current before tripping magnetically — right for motor starters, small transformers, and lighting banks where the startup surge is higher than a resistive load but not extreme. The 4-pole format covers three-phase plus neutral, common in North American 480Y/277 V distribution panels. The 16 A rating and 10 kA interrupting capacity make it a fast mover for panel spares — keep one on the shelf if your line runs 16 A branch circuits.

Frequently asked questions
Where can I buy S204-C16 and how do I get a price?
The S204-C16 is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.
What is S204-C16's listed amps on this component line?
The S204-C16 is rated 16 A.
What is S204-C16's listed type on this component line?
The S204-C16 is a Trip Curve C miniature circuit breaker.
Will S204-C16 drop into a panel that was specified around S204-B32 without rewiring?
Physically yes — both are 4-pole DIN-rail mount with the same 277 VAC rating and 10 kA interrupting capacity. But electrically no: the S204-C16 is 16 A Curve C, while the S204-B32 is 32 A Curve B. The trip curve and ampacity are different, so you'd need to verify the branch circuit load and coordination study before swapping.
What compliance documentation does ABB provide for S204-C16?
ABB's System pro M compact series carries IEC/EN 60898-1 and IEC/EN 60947-2 certifications. RoHS and REACH declarations are available from ABB. Specific documentation for this order code can be requested at quote time.
