Product details

It snaps onto a 35 mm DIN rail per DIN EN 60715 and can also be screw-mounted, with the mounting position flexible enough to allow ±180° rotation on a vertical surface and ±22.5° tilt forward or backward — useful when you're fitting it into a tight gland-plate layout or a swing-frame sub-panel. The coil pulls 10 A at 24 V rated value, and the contactor carries a 2 hp rating at 230 V and 3 A at 400 V.

Integration into the panel — DIN rail, spacing, and wiring

At 45 mm wide, 102 mm tall, and 97 mm deep, the S0 footprint is compact enough for a 600 mm deep enclosure with room for gland plates and wireways. For paralleled conductors, it accepts 2x (0.5 to 2.5 mm²). That's the minimum air gap to adjacent metalwork or another device; factor it into your DIN-rail fill calculation so you don't crowd the arc chamber or block cooling airflow. The arcing time is 10 to 10 ms, and the switching frequency maxes out at 1000 1/h for AC-1, AC-2, and AC-3 duty, dropping to 300 1/h for AC-4 (the heavy jogging/reversing duty).

Frequently asked questions

What is the depth of 3RT2024-2AL20-ZW97?

The depth is 97 mm, with a width of 45 mm and height of 102 mm — the standard S0 frame size for Siemens SIRIUS contactors.

What wire sizes does the spring terminal accept?

The spring-type terminals accept solid or stranded conductors from 1 to 10 mm², and for paralleled conductors, 2x (0.5 to 2.5 mm²).
