Two poles occupy a 36 mm width at 9 mm per pole — plan the gland plate fill factor accordingly. The 230 V AC rating covers single-phase line-to-neutral circuits common in control panel distribution. Rated for 10 A continuous; no derating needed at 40 °C ambient for resistive loads, but motor circuits with repetitive high-inrush may need a one-step upsizing on the breaker. ## Sibling comparison — S202M-C10 The closest functional peer is the S202M-C10, a 2-pole 10 A unit with a C curve. The C curve trips at 5–10× rated current for general-purpose distribution; the K curve on the S802S-K10 trips at 8–12× rated current, better suited for motor and transformer loads. The S202M-C10 carries only 6 kA interrupting capacity at 277 V AC versus the S802S-K10's 50 kA at 230 V AC — a substantial difference for high-fault panels. If the panel was specified around the S202M-C10, the S802S-K10 will physically fit the same DIN rail footprint and same 2-pole wiring, but the trip curve and interrupting capacity differ enough that a design review is needed before substitution.","metaTitle":"S802S-K10 ABB 2-pole MCB, 10 A Trip Curve K, 50 kA","metaDescription":"ABB S802S-K10 miniature circuit breaker, 2-pole, 10 A, Trip Curve K, 230 V AC, 50 kA interrupting capacity.
