It carries a rated insulation voltage of 1000 V and is rated for AC-3e duty up to 1000 V maximum, meaning it handles the inrush and break of squirrel-cage motors within that voltage envelope. The S3 frame size (70 mm wide, 146 mm tall, 139 mm deep) fits standard 35 mm and 75 mm DIN rail via screw and snap-on mounting, with side-by-side mounting permitted for multi-contactor assemblies.
The contactor's switching frequency depends on the duty category. At AC-1 it manages up to 900 operations per hour; at AC-3 the maximum is 850 operations per hour.
Power ratings and thermal derating
Motor power ratings are given at 60 °C ambient: 38 kW at 230 V, 66 kW at 400 V, and 114 kW at 690 V. The 690 V rating of 25.4 kW at 50 Hz (likely a different duty or temperature basis) shows the derating curve matters — always size against the 60 °C column for panels with elevated internal temperatures. Conductor sizing follows: at 40 °C the minimum permissible cross-section is 50 mm²; at 60 °C it rises to 35 mm² (solid/stranded 2x 2.5…16 mm² per terminal, or AWG 2x 10…1/0).
Control circuit and auxiliary contacts
The control coil draws 6 A at 24 V, 6 A at 230 V, 3 A at 400 V, 1 A at 110 V, and 0.3 A at 220 V (all 50 Hz). The product extension for auxiliary switches is available, and both main and auxiliary/control circuits use screw-type terminals — no spring-cage option on this variant. For the main current circuit, screw terminals accept 2x (2.5…16 mm²) solid/stranded or 2x (10…1/0) AWG.
