Product details

The ABB S803C-C63 is a 3-pole 63 A miniature circuit breaker with a C-trip curve, rated for 230 VAC and interrupting 15 kA.

63 A at 230 VAC with a C-curve means it holds through motor inrush (5–10× rated current) and trips on sustained overloads — typical for pump, fan, and compressor branch circuits in a control panel. The 15 kA interrupting rating at 230 VAC covers most industrial fault levels upstream of a distribution transformer; the 10 kA DC rating handles battery-backed DC bus protection.

Integration note

DIN-rail mounted, 3-pole form factor. The 63 A rating and C-curve make it a direct drop-in for a panel originally specified with the 2-pole S202M-C63 — same curve, same interrupting DC rating, just one more pole for three-phase loads. No rewiring of the busbar arrangement needed if the panel already carries a 3-pole breaker.

Frequently asked questions

What is S803C-C63's listed amps (63) on this component line?

The S803C-C63 is rated for 63 A continuous current.

What is S803C-C63's listed type (Trip Curve C) on this component line?

The S803C-C63 uses a C-trip curve, meaning it trips at 5–10× rated current — suited for motor and transformer loads with moderate inrush.

Will S803C-C63 drop into a panel that was specified around S202M-C63 without rewiring?

Yes — same DIN-rail footprint, same C-curve, same 63 A rating, and same 10 kA DC interrupting. The S803C-C63 adds a third pole for three-phase loads, so it fits a panel originally laid out for the 2-pole S202M-C63 as long as the busbar and wiring support three poles.

Where can I buy S803C-C63 and how is it quoted?

The S803C-C63 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
