The K curve provides a higher magnetic trip threshold than a standard B or C curve — typically 8 to 12 times rated current — making it suitable for loads with moderate inrush, such as motor circuits, transformers, and solenoid valves where you need to ride through the startup spike without nuisance tripping. Rated 240 VAC / 110 VDC, it covers single-phase AC branch circuits and DC control loops common in industrial panels. The 2-pole construction lets you switch both line and neutral in a single module, or use it as a double-pole DC disconnect.
Terminals accept 1–25 mm² conductors; torque to 2.5 Nm.
