The 3RT1017-1AH02: The 5.5 kW at 400 V AC-3 rating is the headline motor-switching capacity — it drives a standard 4-pole induction motor up to that load. The 24 VDC coil draws the listed holding current; verify your control transformer and rectifier can supply the inrush without dropout. Type 2 coordination (no-weld fault clearing) requires a 20 A gL/gG fuse upstream per the spec. Type 1 coordination allows a 35 A gL/gG fuse. The S00 frame is 45 mm wide, 57.5 mm tall, and 72 mm deep — a compact footprint that fits tightly packed DIN-rail panels. Finger-safe IP20 protection on the front and terminals means it can be installed in open panels without additional shrouding.
