Its rated operational voltage on the power circuit is 690 V AC at 50/60 Hz, and it carries a utilisation category of AC-3 at ≤440 V with a rated current of 12 A — the figure that governs motor switching duty. The coil is 12 V DC.
AC-3 at 12 A means this contactor is sized for switching squirrel-cage motors up to roughly 5.5 kW at 400 V — the standard motor-load category where inrush is handled without welding the contacts. The reversing configuration (preassembled with reversing power busbar per) interlock-protects the forward and reverse contactors, so no external mechanical interlock is needed for direction control. IP20 per VDE 0106 means it is finger-safe but not sealed; install inside a panel or enclosure rated to the environment.
Altitude derating starts above 2000 m. Mechanical robustness is specified per IEC 60068-2-27 and -2-6: the contactor withstands 15 Gn shocks (11 ms) on Z axis when closed, and 4 Gn vibration from 5 to 300 Hz when closed. Flame retardance meets UL 94 V1 and NF F 16-101/102. Protective treatment is TC per IEC 60068 and DIN 50016, indicating resistance to tropical climates.
