Product details

It carries a MicroLogic 5.0 A electronic trip unit rated 1000 A at 50 °C, with LSI protection (long-time, short-time, instantaneous). Rated breaking capacity reaches 85 kA Icu at 220/240 V AC and 50 kA Icu at 380/415 V AC per IEC 60947-2 — enough for high-fault distribution panels where fault currents can exceed 50 kA at the main incoming. The electronic trip unit includes thermal memory (20 mn) to prevent immediate reclose after a sustained overload, and an LCD display for ammeter readout. Four red LEDs signal fault type; one yellow LED indicates overload.

Fixed backplate mounting, front connection both top and bottom. Width 280 mm, height 327 mm, depth 147 mm — allow 70 mm connection pitch for busbar or cable lugs. IP40 enclosure protection; IK07 impact resistance. Neutral is on the left.
