It's a single-pole thermal-magnetic breaker rated 32 A at 50 °C per EN/IEC 60947-2, with a D trip curve — meaning its magnetic trip threshold is 12 x In (±20 %), so it handles high inrush currents from motor or transformer loads without nuisance tripping.
Breaking capacity: 10 kA Icu at 240 V AC phase-to-neutral, and 3 kA Icu at 415 V AC phase-to-neutral, both per EN/IEC 60947-2. The service breaking capacity (Ics) is 75 % of those values — 7.5 kA at 240 V, 2.25 kA at 415 V. The IP20 finger-safe terminals are fine for enclosed panels; don't use it in a wet location without an outer enclosure. The toggle gives clear ON/OFF indication and a contact position indicator confirms the state even if the toggle is forced.
Snaps onto 35 mm symmetrical DIN rail. Occupies 2 x 9 mm pitches (18 mm wide) — one standard module width for a single-pole breaker. Height 81 mm, depth 73 mm. Tunnel terminals accept 1.5 to 35 mm² rigid or flexible (with or without ferrule); strip length 14 mm, torque to 3.5 N·m. That's a solid grip for a 32 A circuit.
