The 4D protected poles and neutral protection set at 1 x Ir make it a straight fit for a 3-phase + N distribution circuit where you want full pole protection.
Mounts fixed to a backplate in either horizontal or vertical orientation — no DIN-rail clip here, so plan for screw-terminal landing on a panel or sub-panel. The 100 mm width, 130 mm height, and 60 mm depth with a 25 mm connection pitch fit standard MCCB cutouts. Front connections on both upside and downside keep wiring accessible for panel builders.
The GoPact MCCB range is Schneider's economy molded-case breaker line for distribution duty, built to EN/IEC 60947-1, -2, and Annex H. The 8000-cycle electrical endurance and 30000-cycle mechanical endurance are typical for this class — fine for infrequent switching in a distribution role, not for motor-starting duty.
