Product details

Switching frequency: 5 000 operating cycles per hour at AC, with 1 200 cycles/h for AC-1 (resistive) and 1 000 cycles/h for AC-3 (motor) duty. The AC-4 maximum is 250 cycles/h — that's the heavy inching or plugging duty, so if your application does frequent reversing or jogging, stay under that ceiling. Coil pickup at 24 V is 6 A; at 110 V it drops to 1 A, and at 230 V it's 6 A again — note the higher inrush at 230 V. Motor power ratings at 60 °C: 18 kW at 230 V, 31 kW at 400 V, 54 kW at 690 V. These are the thermal continuous ratings — size your motor load against these, not the 40 °C figures, if your panel ambient runs warm.

Main circuit terminals are screw-type, accepting 2x 0.75–16 mm² solid or stranded, or 2x 18–2 AWG. At 60 °C the minimum wire size is 10 mm². The 55 mm width and 115 mm depth fit standard enclosure depths. An auxiliary switch can be added via the product extension slot, so you can add status feedback without external relays.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 55 mm, depth is 115 mm, height is 112 mm. The contactor mounts on a 35 mm DIN rail per EN 50022.

Will this contactor fit a panel designed for the 3RT1034-1AN60-1AA0?

Both are SIRIUS contactors, but the 3RT5034-1AG20 is size S2. The 3RT1034-1AN60-1AA0 is a different frame size; you would need to verify panel cutout and wiring layout against the S2 dimensions (55 mm wide, 115 mm deep) before assuming a direct drop-in.
