It breaks fault currents up to 15 kA per EN 60898 and 20 kA per IEC 60947-2 at 240 V AC, making it suitable for industrial panel protection where the prospective short-circuit current sits between those two standards' test conditions.
The 15 kA breaking capacity under EN 60898 is the value used for residential and light commercial coordination; the 20 kA figure under IEC 60947-2 is the industrial rating, tested with a different power-factor and making-capacity sequence. If your panel SCCR study calls for 18 kA at the loadcenter, the 60947-2 rating covers it; if the spec references EN 60898 only, the 15 kA limit governs. The 1-pole design occupies one modular width unit (18 mm) on the DIN rail, with a depth of 76 mm and an installation depth of 70 mm — standard for a 1 MW device, so it fits existing Betagard or SENTRON distribution boards without re-spacing. In a multi-pole assembly, sum the per-pole losses for thermal derating inside a crowded enclosure.
Integration notes
The 18 mm width (1 MW) matches the Betagard and SENTRON modular grid; downstream neutral bars and busbar systems designed for 1-pole spacing accept it without adapters. Sealable per the spec, so the installer can lock the toggle position after commissioning to prevent unauthorized switching.
