800 A solar-grade MCCB with LSI electronic trip
The Schneider Electric SOL80N3E800 is a 3-pole EasyPact Solar MCCB rated 800 A at 40 °C, with a 50 kA breaking capacity at 800 V AC — that N performance level means it clears faults up to 50 kA without upstream coordination issues in most solar distribution panels. The electronic ETU trip unit gives you LSI protection (long-time, short-time, instantaneous) plus thermal memory, so it tracks real heating in the conductor, not just peak current. Rated operational voltage is 800 V AC 50/60 Hz per EN/IEC 60947-2, with an insulation voltage of 1250 V AC — headroom for high-impedance ground faults common in PV arrays.
Fixed backplate mount, 180 mm wide × 250 mm high × 105 mm deep, with a 40 mm connection pitch. Mounts horizontal or vertical; pollution degree 3 (IEC 60664-1) means it tolerates conductive dust in unsealed enclosures.
