SIRIUS capacitor contactor, S0 frame
It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022, with a 45 mm width and 155 mm depth, which means it fits standard 45 mm-wide DIN-rail slots and leaves room for adjacent devices in a crowded enclosure. Rated for AC coil voltage, the contactor switches 6 A at 230 V AC, 3 A at 400 V AC, and 1 A at 690 V AC — these are the currents it can make and break when switching capacitor banks, not motor loads. The coil is screw-type terminated, so expect to torque down ring or fork terminals rather than push in ferrules.
Wiring and integration
Terminals accept solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm². For stranded wire, the range is 2x (1...2.5 mm²) or 2x (2.5...10 mm²). The higher stranded capacity (10 mm²) is rated at 60 °C ambient, so if the panel runs hot, you can land a single 10 mm² on each terminal. At 40 °C ambient, the same terminal accepts 1x 10 mm² solid.
