The S202P-K32A: Used in final distribution circuits feeding inductive loads — small motors, contactor coils, solenoid valves — where the K curve's higher magnetic trip threshold avoids nuisance trips on startup inrush. The neutral pole switches the neutral, so it is suited for single-phase circuits where both line and neutral need overcurrent protection.
Lifecycle stage is current — ABB has not issued a phase-out or last-time-buy notice for this order code. That means it is still a standard catalog item, not a legacy spare you need to hunt on the surplus market. For a maintenance-spares purchaser, this is the kind of part you keep one in the cabinet for, not the one that keeps you up at night.
