It is rated for AC-1 utilisation category at 85 A up to 415 V, meaning it is designed for resistive loads — heaters, ovens, lighting banks — where inrush current is minimal and the switching duty is steady-state make-and-break. The contactor carries EN/IEC 60947-4-1 and GB/T 14048.4 certification, which covers the standard for contactors and motor-starters in industrial control panels. Mounting is via DIN rail or plate, so it fits standard panel layouts.
For motor loads (AC-3 duty) this contactor is not rated, so it should not be specified for inductive starts. The 4P 4NO configuration gives four independent normally-open pole sets, each rated for the full 85 A in AC-1.
