Product details

It carries a rating of 18.5 kW at 500 V in AC-3 duty — that's the standard motor-switching category per IEC 60947-4-1, so this contactor handles the inrush and break of a three-phase induction motor up to that power without welding the main contacts. For AC-2 duty (slip-ring motors, or where the load is mostly resistive during switching) it's rated 15 kW at 400 V.

Mounting and wiring — what fits

Auxiliary and coil wiring takes solid conductors 2x 0.25 to 2.5 mm².

Switching frequency and auxiliary ratings

Maximum mechanical switching frequency is 10 million operations typical. Electrical frequency depends on duty: 1200 cycles/hour at AC-1 (resistive), 1000 at AC-3 (motor), 250 at AC-4 (plugging/reversing). The built-in auxiliary contacts are rated 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC — enough for PLC inputs or relay coils in the control circuit.

Frequently asked questions

How do I get current pricing and availability for 3RT1034-3AG60?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels — no automated price or lead time is published here.

What is 3RT1034-3AG60's listed depth?

The depth is 115 mm. Overall dimensions are 112 mm height by 55 mm width, fitting the S2 contactor footprint.

What wire sizes does the 3RT1034-3AG60 accept?

The main power terminals accept stranded conductors up to 2x 25 mm². Auxiliary and coil terminals accept solid conductors 2x 0.25 to 2.5 mm². All terminals are screw-type.

Will 3RT1034-3AG60 drop into a panel specified around 3RT5034-1BW40 without rewiring?

The 3RT1034-3AG60 is a size S2 contactor with screw terminals and DIN-rail snap-on mounting. The 3RT5034-1BW40 is a different frame generation — verify the mounting hole pattern and terminal spacing against your existing panel layout before ordering. The terminal wire ranges are similar, but the physical footprint may differ.

What compliance documentation does Siemens provide for 3RT1034-3AG60?

As a current SIRIUS catalog product, this contactor carries CE marking for the European market and is designed to meet IEC 60947-4-1. UL and CSA listings are typical for this series but should be confirmed against the specific variant. RoHS and REACH declarations are available from Siemens documentation.
