Curve K is designed for loads with moderate inrush — typically motor circuits, transformers, or solenoid valves — where the magnetic trip threshold sits between 8 and 12 times rated current, avoiding nuisance trips on startup while still providing short-circuit protection.
Snap-on DIN rail mounting per EN 60715. The 4-pole footprint occupies four module widths (72 mm on a standard DIN rail). Rated 277 VAC line-to-neutral or 480Y/277 VAC three-phase systems — common in North American lighting and small motor panels. The S200P series uses tunnel terminals accepting up to 25 mm² conductor; torque to 2.8 Nm.
