Product details

Integrator's note on the 3RT2017-2FF42

It snaps onto 35 mm DIN rail per DIN EN 60715 and can be mounted in any orientation within ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward — useful when panel space forces a non-standard angle. Rated switching frequency at AC-3 duty (motor loads) is 750 operations per hour, and at AC-4 (plugging/inching) it drops to 250 ops/h. The DC coil drop-out time spans 38 to 65 ms; arcing time runs 10 to 15 ms. The 230 V rating is expressed as 2 hp, matching typical single-phase motor loads in that voltage class.

Spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², or two conductors of the same cross-section (2x 0.5 to 4 mm²). Strip length and ferrule spec follow the usual spring-cage practice — no tool needed beyond a screwdriver for the release slot.

Frequently asked questions

What are the key electrical ratings for this contactor?

The coil is 110 V AC. At AC-3 motor duty it handles 750 operations per hour; at AC-4 (plugging) 250 ops/h. DC switching capacity: 10 A at 24 V, 2 A at 48 V, 1 A at 110 V, 0.3 A at 220 V. AC ratings include 3 A at 400 V and 2 hp at 230 V.

What wire sizes does the spring terminal accept?

Solid or stranded wire from 0.5 to 4 mm², and two conductors of the same cross-section (2x 0.5 to 4 mm²).

What mounting clearances are required?

Minimum clearances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm to the side. The contactor can be mounted on 35 mm DIN rail and rotated ±180° on a vertical surface, with ±22.5° forward/backward tilt allowed.
