It's rated for 10 A at 24 V on the auxiliary contacts, and the main contact switching frequency reaches 1 000 cycles per hour under AC-1 resistive load, 750/h under AC-3 motor duty, and 250/h under AC-4 plugging/inching — so the AC-4 figure is the one that governs frequent reversing or jogging applications. Mounting is screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a ±180° rotation possible on a vertical surface and ±22.5° tilt forward/backward. Wire range accepts 0.5 to 4 mm² solid or stranded, or 2x (0.5 to 4 mm²) in the same clamp.
Sourcing & Lifecycle — Active Production, Critical Spare Ready
The 3RT2017-2AH02 carries an auxiliary switch built in, so it's ready for feedback to a PLC or status lamp without an add-on block. That saves a part number on the BOM and one wiring step during commissioning.
Integration — Panel Fit and Wiring Notes
Spring-type terminals on the coil mean no screwdriver needed for the control wiring — strip 8 mm, push in. The main contacts accept the same 0.5–4 mm² range, so a 2.5 mm² motor feed fits without ferrule if solid. The 45 mm width leaves room alongside a motor-protective circuit breaker in a typical starter combo. Auxiliary contact ratings: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The 230 V rating is given as 2 hp — useful for direct-on-line motor starting in North American panels where horsepower is the common spec.
