Product details

What it is and where it goes

The ABB S263-C63 is a DIN-rail mount miniature circuit breaker (MCB) from the S260 series, rated at 63 A with a C-trip curve. It snaps onto standard 35 mm DIN rail inside a distribution board or control panel, protecting downstream wiring and loads against overcurrent and short circuits. The C-curve characteristic means it holds through moderate inrush (typical of motor starters and transformers) and trips on sustained overload at 5–10× rated current — a good fit for mixed resistive-inductive loads out here in the grease.

Frequently asked questions

Where can I buy the S263-C63 and get current pricing?

The S263-C63 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.

Will the S263-C63 fit in a panel designed for the S273-K6A?

Both are three-pole DIN-rail breakers sharing the same 18 mm per-pole width and standard 35 mm rail footprint, so the S263-C63 will physically drop into the same panel slot without rewiring. The key difference is the trip curve and current rating — the S263-C63 is a 63 A C-curve, while the S273-K6A is a 6 A K-curve (a steeper magnetic trip for semiconductor protection). Verify the required curve and ampacity for your load before swapping.
