Siemens SIRIUS 3RT1015-1HB42-ZW95 contactor, AC-3 3 kW/400 V, 1 NC, DC 24V coil, 0.7...1.25*US, 3-pole, Size S00, screw connection, multi-unit packing of 144.
The DC 24V coil with a control range of 0.7 to 1.25 times the rated control supply voltage gives a consistent pick-up margin even if the panel supply sags. One normally-closed auxiliary contact is built in, which is often used as a feedback interlock or for a status signal to the PLC.
The coil is DC 24 V with a control range of 0.7 to 1.25 times the rated control supply voltage, so it picks up reliably from about 16.8 V to 30 V DC.
It is rated for AC-3 duty at 3 kW / 400 V, which covers three-phase induction motors up to that power at 400 V line voltage.
Yes, it comes with one normally-closed (1 NC) auxiliary contact built in.
