The 3RT2017-2KF42: At 45 mm wide, 70 mm tall, and 73 mm deep, it fits standard control panel rail spacing without crowding adjacent devices. No screwdriver needed for termination; just strip and push. Clearance requirements are modest: 10 mm upwards, forwards, and downwards, plus 6 mm at the sides.
Load switching and duty cycles
Main contacts are rated 20 A at the top end and 12 A at the lower bound — the actual continuous current depends on the duty class and ambient temperature. For motor loads, the 230 V horsepower rating is 2 hp, which lines up with typical small pump or fan applications in the S00 frame. The arcing time runs 10 to 20 ms depending on the DC load inductance — factor this into the circuit protection coordination.
Coil and environmental specs
No auxiliary switch is built in, so if you need status feedback or a holding contact, plan for an external add-on block.
