Product details

Coil voltage range is 200–277 V AC/DC. Screw-type coil terminals and screw fixing mounting — expect a solid panel mount, not a DIN-rail clip. The contactor carries an auxiliary switch and accepts stranded cable up to 240 mm² on the main poles.

Dimensions: 210 mm high, 165 mm wide, 202 mm deep. The S10 frame is one of the larger contactor footprints — plan for a 202 mm depth behind the panel door.

Duty and switching performance

Switching frequency varies by duty: AC-1 (resistive) up to 800 operations/hour, AC-3 (motor starting) up to 700 ops/h, AC-4 (plugging/inching) up to 130 ops/h. Mechanical life typical: 10 million operations.

Frequently asked questions

What is the depth of the 3RT1065-6QP35?

The depth is 202 mm.

What stranded wire range does the 3RT1065-6QP35 accept on the main poles?

The main poles accept stranded cable from 70 mm² up to 240 mm².

Can the 3RT1065-6QP35 be mounted in any orientation?

Mounting position allows vertical surface mounting with ±90° rotation and ±22.5° tilt forward/back. Minimum clearances: 10 mm up/down, 20 mm forward, 10 mm at the side.

Where can I buy the 3RT1065-6QP35?

The 3RT1065-6QP35 is sourced to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time.
