Coil and switching characteristics
The 3RT2017-2KF41-1AA0: Coil pickup is rated at 110 VDC with a 0.7 initial voltage factor — meaning it pulls in reliably at 77 VDC and holds in. The contactor operates across -25 to +60 °C ambient, with storage range of -55 to +80 °C. Mechanical life is typical 30 million operations. Switching rates vary by duty: AC-1 (resistive) allows 1 000 cycles/hour, AC-2 and AC-3 (motor) 750 cycles/hour, and AC-4 (plugging/inching) 250 cycles/hour. Arcing time is 10 to 15 ms; DC switching times run 7 to 20 ms. The auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V — check the specific DC load curve for your circuit.
Termination and wiring
Spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) per clamp. No auxiliary switch block is included — this is a bare coupling contactor. Panel clearance: 10 mm upwards, 10 mm forwards, 6 mm sideways, 10 mm downwards. Overall dimensions: 45 mm wide, 70 mm tall, 73 mm deep. Size S00 footprint fits standard 45 mm-wide DIN-rail slot.
