Product details

What it is and what it does

The Siemens 3RT5034-1AH00 is a SIRIUS power contactor in the S2 frame size, designed for switching motor loads in industrial control panels. It is rated for 31 kW at 400 V at 60 °C (AC-3 duty), which means it handles the inrush and running current of a standard three-phase induction motor up to that power level. The contactor uses screw-type terminals for both main and auxiliary circuits, accepting wire sizes up to 2x 16 mm² solid or stranded.

Panel fit and mounting

Mounts on 35 mm DIN rail per DIN EN 50022, with screw and snap-on fastening. The 55 mm width and 115 mm depth fit standard enclosure gland-plate layouts; side-by-side mounting is permitted without derating for the thermal ratings listed. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, so panel layout is flexible.

Sourcing and availability

Sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time. No production discontinuation is announced; the part remains a standard catalog item.

Frequently asked questions

Where can I buy 3RT5034-1AH00 and how do I get a price?

This part is sourced to order against an RFQ. Submit a request for quote; availability and current pricing are confirmed at that time.

What is 3RT5034-1AH00's listed depth and width?

Depth is 115 mm; width is 55 mm.

Will 3RT5034-1AH00 drop into a panel specified around 3RT5034-1AP00 without rewiring?

Both are size S2 contactors with identical mounting footprint and screw-type terminals, so mechanical fit and wiring are the same. The difference is in the coil voltage — the 1AH00 uses a different coil rating than the 1AP00; verify coil compatibility before substitution.

What compliance documentation does Siemens provide for 3RT5034-1AH00?

The part is RoHS compliant per the substance prohibitance date of 03/01/2017. It also carries a surge voltage resistance of 6 kV and is rated for pollution degree 3. Full declarations are available from Siemens on request.
