Product details

Rated for AC-4 duty at 35 A and 400 V, this contactor handles the severe switching conditions of motor reversing or plugging — where the contacts make and break locked-rotor current. For standard motor starting (AC-2), it carries 18.5 kW at 400 V, and at 500 V it delivers 22 kW, with a 690 V rating of 11.4 kW. The front face is IP20, while the terminals are IP00 — standard for panel-mounted contactors where the enclosure provides the overall protection. Pollution degree 3 suits industrial environments with conductive contamination. Side-by-side mounting is permitted, which simplifies multi-contactor panels.

Main circuit screw terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (0.75 to 25 mm²) stranded wire. The auxiliary circuit accepts 2x (0.75 to 16 mm²) solid or stranded. This range covers standard panel wiring from signal-level to motor power conductors.

Frequently asked questions

How do I get current pricing and availability for 3RT1035-3AG14?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — both are confirmed at quote time.

What is 3RT1035-3AG14's depth?

The depth is 164 mm.

What solid wire sizes does the main circuit accept?

The main circuit screw terminals accept 2x (0.25 to 2.5 mm²) solid wire.

Will 3RT1035-3AG14 drop into a panel specified around 3RT1044-1FB46 without rewiring?

The 3RT1035-3AG14 is a smaller S2-frame contactor compared to the S3-frame 3RT1044-1FB46. The mounting rail and terminal layout differ — expect to rework the panel layout and wiring.

What compliance documentation does Siemens provide for 3RT1035-3AG14?

Siemens typically provides RoHS and REACH declarations, plus UL and IEC certifications. Specific documents are available on request with the RFQ.
