The 2 A thermal element (rated at 2.1 A thermal trip) sets the continuous current ceiling. On a 277 VAC line-to-neutral circuit, that's about 480 VA per pole — sized for control transformers, contactor coils, or small power supplies. The K-curve's magnetic trip at 8–12× In (16–24 A) means it holds through the 6–8× locked-rotor current of a fractional-horsepower motor or the magnetizing surge of a 50 VA control transformer, yet clears a hard short fast. The S202P-K2 carries a current-production lifecycle status. No official successor exists because the part remains in the active S200P catalog. The IP20 finger-safe enclosure (IP40 with supplied cover) suits indoor switchgear; the black actuator is sealable for lockout/tagout. The 35 mm width matches a 2-module footprint — plan for 3-pole or 4-pole siblings to occupy adjacent slots if ganging is needed.","metaTitle":"ABB S202P-K2 MCB 2P K 2A 277VAC DIN Rail, 10 kA","metaDescription":"ABB S202P-K2 miniature circuit breaker, 2-pole, K-curve, 2 A, 277 VAC, 10 kA interrupting rating.

The K-curve holds through startup surges without nuisance tripping."},{"question":"Where can I buy S202P-K2?","answer":"The S202P-K2 is sourced and quoted to order against an RFQ through independent distribution.

The S202P-K2 is 2-pole, 2 A, K-curve. The pole count, current rating, and trip curve are all different; the panel would need rewiring and the branch circuit re-evaluated."},{"question":"What compliance documentation does ABB provide for S202P-K2?","answer":"ABB provides RoHS, REACH, UL, and IEC compliance documentation with the product.
