Product details

The AC-4 rating of 29 A at 400 V covers inching and plugging duty, where the contactor interrupts stalled-rotor current each cycle.

The 55 mm width and 112 mm height fit standard S2 panel cutouts. Front-face protection is IP20, which keeps fingers off the terminals inside the enclosure.

Wiring and Terminal Capacity

For control wiring, the coil terminals take 2x 0.5–1.5 mm² solid or 2x 0.75–2.5 mm² stranded, with a maximum of 2x 4 mm². The power circuit can take stranded up to 25 mm² — enough for the full rated current without doubling up.

Frequently asked questions

What are the key electrical ratings for the 3RT1034-1AF04?

AC-2 motor switching at 400 V is rated at 15 kW. AC-4 inching duty at 400 V is rated at 29 A. The coil draws 10 A at 24 V and 6 A at 230 V. Mechanical life is 10,000,000 operations typical.

What compliance documentation does this brand provide for 3RT1034-1AF04?

The part is RoHS compliant with a substance prohibition date of May 1, 2012. Pollution degree 3 per IEC 60947-1 is confirmed for industrial environments.
