It carries an 11 kW rating at 500 V and 690 V, with a 24 V 50/60 Hz coil. The S0 frame means it fits the standard 45 mm width slot on a DIN rail, sharing the footprint with other SIRIUS components in the same panel layout.
The 11 kW rating at 500 V and 690 V tells you this contactor handles standard three-phase induction motors up to that power at those voltages — typical for European 400/690 V networks. For AC-2 duty (slip-ring motors or wound-rotor applications), it also delivers 11 kW at 400 V. The coil pulls 10 A at 24 V on pickup, which is the inrush — steady-state holding current is lower. The 0.8 to 1.1 operating range at 50 Hz and 0.85 to 1.1 at 60 Hz means the coil holds in down to about 19.2 V at 50 Hz, which is useful if your control transformer sags under load.
The 45 mm width and 85 mm height with 91 mm depth fit standard S0 enclosure cutouts. Front face is IP20, terminals are IP00 — so the panel door provides the touch protection.
Main terminals accept screw-type connections: solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). For stranded or ferruled wire, use 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8.
