Its headline rating is 700 A in AC-3 utilisation category (IEC 60947-4-1), which translates to switching a 250 kW induction motor at 400 V AC — the AC-3 curve governs starting and plugging of squirrel-cage motors, where the contactor makes and breaks the motor at full load. For resistive loads (AC-1), the thermal current Ith is 700 A at 50 Hz, with 88 W dissipation per pole. The 400 V DC coil (Uc) holds at 0.85 to 1.1 Uc and drops out between 0.2 and 0.35 Uc, so verify your control supply stays within that band at 55 °C ambient. Mounting is plate-based (not DIN rail), with power circuit connections via bar (40 x 5 mm busbar) or ring lugs up to 240 mm². The control circuit uses screw clamp terminals accepting 1 to 4 mm² flexible or solid. IP20 front-face protection with shrouds per IEC 60529 means it's suited for enclosed panel installation, not washdown environments.
