It is sized for inductive loads with moderate inrush — motor starters, transformers, and solenoid valves — where a Curve C might nuisance-trip on startup but a Curve D would be too slow for downstream protection. On a 20 A frame, that magnetic trip threshold sits well above the steady-state draw but still clears a hard short within a half-cycle. The 2-pole footprint matches the standard modular width (2 × 17.5 mm = 35 mm). No special busbar required for single-phase feed — the line and load side accept fork or pin terminals directly.","metaTitle":"S802S-K20 Miniature Circuit Breaker, 20 A, 2-Pole, Curve K,","metaDescription":"S802S-K20 miniature circuit breaker, 20 A, 2-pole, Trip Curve K, 230 VAC, 50 kA interrupting rating.
