The S202-D4 is a 4 A, 2-pole miniature circuit breaker in the ABB S200 series, with a D trip curve and a 277 V AC rating.
The 2-pole format takes two module widths (about 36 mm) in the enclosure. No separate busbar needed for the line side — the S200 busbar system clips directly into the breaker's line-side terminals for multi-pole feed.
The S202-D4 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The D trip curve on the S202-D4 means the magnetic trip operates at 10 to 20 times the rated current (40 to 80 A), designed for loads with high inrush like motors, transformers, or welding equipment.
The S202-D4 has a 6 kA interrupting rating at 277 V AC, meaning it can safely interrupt fault currents up to 6,000 A without damage.
Yes. Both the S202-D4 and S202M-C10 share the same 2-pole DIN-rail footprint, same 277 V AC voltage rating, and same 6 kA interrupting rating. The only difference is the trip curve — D on the S202-D4 versus C on the S202M-C10 — and the current rating (4 A versus 10 A). The physical fit and wiring are identical.
