The Siemens 3RT1316-1AN20 is a SIRIUS power contactor in Size S00, with four normally-open main contacts rated for 4 kW at 400 V in AC-2 duty — the standard category for slip-ring motor starting and reversing.
If your motor is a standard induction machine, you can still use it, but the thermal capacity is higher than needed. The 24 VDC coil with 10 A holding current means the control transformer or power supply must deliver that inrush; verify the DC supply is stiff enough to avoid voltage droop on a multi-contactor bank. The screw terminals accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or a single 4 mm² conductor. That covers most control and power wiring in a standard panel.
That matters when you're designing a motor branch circuit and want to avoid nuisance trips or unnecessary contactor swaps.
