Product details

SIRIUS S2 power contactor — panel fit and ratings

The Siemens 3RT5034-1AQ00 is a SIRIUS S2-size power contactor rated for main circuit switching up to 690 V insulation voltage with 6 kV surge resistance. The depth is 115 mm, which matters when you're planning gland-plate clearance or door swing on a compact enclosure.

Main current circuit and auxiliary/control circuit both use screw-type terminals. Main contacts accept 2x (0.75... 16 mm²) solid or stranded, or 2x (18... 2) AWG. At 40 °C minimum permissible cross-section is 16 mm²; at 60 °C derate to 10 mm². Auxiliary switch extension is supported.

Frequently asked questions

Where can I buy 3RT5034-1AQ00?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3RT5034-1AQ00 drop into a panel specified around 3RT5034-1AR60 without rewiring?

Both are S2-size SIRIUS contactors sharing the same 55 mm width, 115 mm depth, and screw/snap-on DIN rail mounting — so the mechanical footprint is identical. The 1AQ00 uses an AC coil (50 Hz rated 380 V); the 1AR60 uses a different coil voltage. Verify coil voltage compatibility before swapping.

What compliance documentation does this brand provide for 3RT5034-1AQ00?

The part carries a substance prohibitance date of 03/01/2017, indicating RoHS/REACH compliance. Standard Siemens SIRIUS documentation includes IEC/EN 60947-4-1 certification for the contactor series.
