It's a 4-pole unit with a D tripping curve and a 6 A rated current at 50 °C per EN/IEC 60947-2.
Breaking capacity is 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V. The rated service breaking capacity (Ics) is 75% of Icu at each voltage level — 15 kA at 240 V, 7.5 kA at 415 V, 4.5 kA at 440 V. That 75% Ics/Icu ratio means after clearing a fault at rated Ics, the breaker is still functional and can be reclosed without immediate replacement. For a panel OEM, that's the difference between a quick restart and a callout to swap a welded contactor.
Width is 72 mm (8 x 9 mm pitches), so it occupies four module spaces. Torque to 2 N·m on the power circuit. IP20 finger-safe protection, pollution degree 3 rated. The toggle gives local ON/OFF indication with a contact position indicator — no guessing whether it's tripped or switched off.
