Product details

Mounting position is standing on a horizontal surface. The 97 mm depth, 102 mm height, and 45 mm width fit standard S0 panel cutouts.

Wire range and auxiliary ratings

Accepts solid or stranded wire from 1 to 10 mm² (single conductor) or 2x (0.5 to 2.5 mm²) for the main contacts. Auxiliary switch is present on this variant. The 24 V rated auxiliary contact carries 10 A; at 48 V it carries 2 A, at 110 V it carries 1 A, at 230 V it carries 0.3 A, and at 400 V it carries 3 A. Arcing time is 10 to 10 ms at AC.

Operating conditions and mechanical life

Mechanical life of the contactor typical is 10,000,000 operations. Maximum switching frequency at AC-1, AC-2, AC-3, and AC-3e is 1,000 1/h; at AC-4 it is 300 1/h.

Frequently asked questions

How do I get current pricing and availability for 3RT2024-2EL20-1AA0?

Submit an RFQ — this part is sourced and quoted to order through independent distribution, with availability and current pricing confirmed at quote time.

What is 3RT2024-2EL20-1AA0's listed depth?

The depth is 97 mm, with a width of 45 mm and height of 102 mm.

What wire sizes does 3RT2024-2EL20-1AA0 accept?

Solid or stranded wire from 1 to 10 mm² for main contacts, and 2x (0.5 to 2.5 mm²) for auxiliary circuits.

Will 3RT2024-2EL20-1AA0 drop into a panel specified around 3RT2016-1AG62?

Both are S0 frame size on 35 mm DIN rail, so the footprint and mounting are identical. However, the coil voltage and terminal type differ — check the coil wiring and auxiliary wiring before substitution.
