Product details

It is rated for distribution duty and carries a 25 kA Icu breaking capacity at 415 V AC (50/60 Hz) per EN/IEC 60947-2.

Breaking capacity steps with system voltage: 40 kA Icu at 240 V AC, 25 kA at 415 V, 20 kA at 440 V, and 15 kA at 500 V.

The thermal element tracks RMS heating; the magnetic pickup is fixed and non-adjustable. Neutral protection is set to no protection (3D) — the neutral pole is switched but not monitored for overcurrent.

Mounts flat on a backplate — no DIN-rail adapter here. Accepts horizontal or vertical orientation. Front connections top and bottom, with a 35 mm connection pitch. IP40 enclosure protection; IK07 impact resistance.

Rated for 50,000 mechanical cycles and 30,000 electrical cycles at rated current (440 V).
