Product details

Clearance requirements are 10 mm upwards, downwards, and forwards, with 6 mm at the side — enough for adjacent devices in a dense panel.

Rated operational current at AC-1 (resistive load) is 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The AC-3 (motor) switching frequency is 1 000 operations per hour maximum, dropping to 300 for AC-4 (inching/jogging). The auxiliary switch is included, and the mechanical life is typical 10 000 000 operations.

Frequently asked questions

What is the closest functional second-source to 3RT2024-1AB00?

The 3RT2025-1AD20-1AA0 is a functional peer in the same SIRIUS Size S0 family, but verify coil voltage and terminal type — the 3RT2024-1AB00 uses screw-type coil terminals, which may differ from the peer's configuration.

What are the mounting clearances for 3RT2024-1AB00?

Clearances are 10 mm upwards, downwards, and forwards, and 6 mm at the side. The depth is 97 mm, width 45 mm, height 85 mm.

What conductor sizes does the 3RT2024-1AB00 accept?

Solid or stranded conductors from 1 to 10 mm² on the main circuit. Auxiliary contacts accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
