Product details

SIRIUS Power Contactor, Size S2 — 3RT1034-3AK60-1AA0

It carries an AC-3 rating of 18.5 kW at 500 V and 10 kW at 690 V, making it a fit for 400 V to 690 V three-phase motor circuits where the load falls within that power band. Screw-type terminals on the main circuit accept solid conductors up to 2x (0.25... 2.5 mm²) and stranded up to 2x (0.75... 25 mm²).

Mounting & Integration

Side-by-side mounting is permitted — no derating gap required for adjacent contactors in the same row, provided ambient stays within the -25 to +60 °C operating range. Dimensions: 55 mm wide, 112 mm high, 115 mm deep.

Switching Performance & Mechanical Life

Maximum switching rates: 1,200 ops/h under AC-1 (resistive), 750 ops/h under AC-2, 1,000 ops/h under AC-3, and 250 ops/h under AC-4 (plugging/inching). Coil operating range is 0.8 to 1.1 x rated voltage at both 50 Hz and 60 Hz.

Frequently asked questions

What are the key ratings for 3RT1034-3AK60-1AA0?

AC-3 motor power is 18.5 kW at 500 V and 10 kW at 690 V. AC-2 rating at 400 V is 15 kW. Mechanical life is 10 million operations. Mounts on 35 mm DIN rail, screw-type terminals, Size S2 frame.

How do I get current pricing and availability for 3RT1034-3AK60-1AA0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels. No online price or live stock count is published for this part.

Will 3RT1034-3AK60-1AA0 drop into a panel specified for 3RT5034-1BW40?

Both are Size S2 contactors on the same 35 mm DIN rail footprint with screw terminals, so the mechanical fit is the same. The 3RT5034-1BW40 is a newer-generation SIRIUS contactor with a different coil system and accessory interface — verify coil voltage compatibility and aux contact arrangements before substituting.
