Spring-loaded terminals on both main and auxiliary circuits accept 2x (0.25 to 2.5 mm²) solid/stranded or 2x (24 to 14 AWG), which saves a screwdriver step during panel wiring. ## Motor duty and coordination At AC-2 duty (slip-ring motors, wound-rotor) the contactor handles 5.5 kW at 400 V. For AC-4 (plugging, inching) the rated operational current is 8.5 A at 400 V — that is the figure to size for reversing or jogging applications. Type 2 coordination requires a 20 A gL/gG fuse; Type 1 allows 35 A. The built-in varistor surge suppressor clips coil transients, so no external RC snubber is needed for the magnet coil. The S00 frame is 45 mm wide, 60 mm tall, 73 mm deep — a compact footprint that leaves room for adjacent devices. Side-by-side mounting is allowed without derating, which simplifies multi-contactor motor starter assemblies. Operating temperature range is -25 to +60 °C, with pollution degree 3 (conductive pollution typical in industrial panels).","metaTitle":"Siemens 3RT1017-2KB41 SIRIUS S00 Power Contactor, 24 VDC, 5.","metaDescription":"Siemens 3RT1017-2KB41 SIRIUS S00 power contactor, 24 VDC coil, 5.5 kW AC-2 at 400 V.
