The Siemens 3RT1017-2GG22 is a SIRIUS power contactor in the Size S00 frame, at 45 mm wide, 60 mm tall, and 114 mm deep. Side-by-side mounting is supported. Spring-loaded terminals on main and auxiliary circuits accept 2x 0.25 to 2.5 mm² solid or stranded. The headline motor ratings: 5.5 kW at 400 V in AC-3 duty (standard squirrel-cage starting) and 5.5 kW at both 500 V and 690 V. That means it handles a 5.5 kW motor on a 400 V line, and the same motor power on higher-voltage networks up to 690 V — useful for 690 V industrial grids common in mining or heavy process. For reversing or inching duty (AC-4), the rating drops to 8.5 A at 400 V, reflecting the higher switching stress of plugging or jogging. The coil operates on 50 Hz at 0.8 to 1.1 A and 60 Hz at 0.85 to 1.1 A, with full-wave rectified DC suppression built in. Coordination matters for selective protection: type 2 coordination requires a 20 A gL/gG fuse upstream; type 1 coordination allows a 35 A gL/gG fuse.
Deployment context
The Size S00 frame fits in compact control panels where every millimeter counts. The 30 million mechanical cycles typical life means it outlasts most machines in light-to-moderate switching duty.
