Motor switching capability and coordination
At AC-4 (plugging, inching, reversing) at 400 V, it handles 8.5 A — this is the rating that governs frequent jogging or reversing applications. For standard squirrel-cage motors, the maximum motor power is 4.5 kW at 500 V and 5.5 kW at 690 V. The main circuit uses screw-type terminals accepting 2x 1 to 2.5 mm², 2x 2.5 to 6 mm², or a single 10 mm² conductor.
Auxiliary contact ratings and environmental limits
The integrated auxiliary contacts (likely 1 NO + 1 NC, though not explicitly counted in the main contact spec) carry 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — sufficient for pilot duty on PLC inputs or small relay coils. Mechanical life is 10 million cycles, typical for the S0 frame. The front face is IP20; the terminals are IP00, meaning the terminal area must be inside a cabinet.
The 45 mm width per unit means a 12-module rail section holds 12 contactors. Depth is 91 mm, height 85 mm — check gland-plate clearance if the rail is near the back wall. The auxiliary contact wiring accepts 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or a single 4 mm² conductor — solid or stranded.
