It mounts on a standard DIN rail, occupies two 17.5 mm module widths (35 mm total), and interrupts fault currents up to 10 kA at 277 VAC.
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.
