On a 10 A breaker, that translates to a magnetic trip threshold around 50 to 100 A, so it holds through short-duration inrush without nuisance tripping on general-purpose branch circuits. Rated insulation voltage is 440 V, and the overvoltage category is III, which means it is rated for fixed-installation distribution boards downstream of the main panel — not just final sub-circuits. The rated short-circuit breaking capacity Icn is 11.2 kA per IEC 60898-1, with an ultimate breaking capacity Icu of 15 kA per IEC 60947-2. Physical fit: 52.5 mm wide (three modular 17.5 mm units), 111 mm tall, 69 mm deep. DIN rail mount, IP20 finger-safe terminals with IP40 front-of-panel protection once installed in an enclosure. The bi-directional cylinder-lift terminals accept a tightening torque up to 2.8 Nm. This is the standard S200 footprint — direct swap into any existing S200 or S200P cutout.
