Integrator's first look
The coil is rated for 50 Hz at 110 V. Rated for AC-3 duty at 7.5 kW on both 500 V and 690 V supplies, and 12.5 A in AC-4 at 400 V — the AC-4 figure governs reversing or inching applications where the contactor makes and breaks stalled-rotor current. The contactor is IP20 on the front, IP00 at the terminals.
The S0 frame measures 45 mm wide, 85 mm high, and 140 mm deep. Screw-type terminals on the main circuit accept solid or stranded conductors: 2x (0.25... 2.5 mm²) for control wiring, and 2x (1... 2.5 mm²), 2x (2.5... 6 mm²), or max. 2x 10 mm² for power. AWG equivalents are 2x (16... 12), 2x (14... 10), or 1x 8 for the main contacts.
