The Siemens SIRIUS 3RT1016-2AP62 is a size S00 power contactor rated for motor switching at 5.5 kW at 690 V and 8.5 A in AC-4 duty at 400 V — the AC-4 figure governs reversing and plugging applications where the contactor makes and breaks stalled-rotor current, so that 8.5 A is the number to size against for frequent jogging or inching cycles. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, matching the panel builder's standard ferrule set without lug crimping.
These values let the panel designer size the branch protection without derating guesswork.
Front face carries IP20 protection — safe for finger contact behind a closed panel door.
