Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a width of 45 mm, height 85 mm, and depth 97 mm — the depth is the dimension to watch when planning cabinet clearance behind the rail. The contactor carries a 10 A rated operational current at 24 V and delivers 2 hp at 230 V, making it a fit for small motor circuits and general switching duties where the S0 footprint is specified. The screw-type coil terminals accept solid or stranded conductors from 1 to 10 mm², with dual-wire capability for 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²).

Switching Performance and Ratings

Rated for AC-1, AC-2, AC-3, and AC-3e duty at up to 1,000 operations per hour; AC-4 duty is limited to 300 operations per hour. Auxiliary switch is included as standard, simplifying integration into control circuits without a separate add-on block.

Frequently asked questions

What are the key dimensions of the 3RT2024-1AL20-ZX95?

Width 45 mm, height 85 mm, depth 97 mm. The depth is the critical dimension for cabinet clearance behind the DIN rail.

What wire sizes does the 3RT2024-1AL20-ZX95 accept?

Solid or stranded conductors from 1 to 10 mm², with dual-wire capability for 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²).
