Product details

It carries a 200-277 V AC coil with screw-type terminals, and the main power circuit accepts stranded conductors from 25 to 120 mm² — sized for the larger motor feeds you'd expect on an S6 frame. The coil pickup threshold is 0.8 of rated voltage, and the full-scale holding factor is 1.1 — standard for this class of contactor.

Wiring & Auxiliary Contacts

The coil terminals accept solid or stranded conductors: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or max 2x (0.75-4 mm²). The main power terminals take stranded 25-120 mm² through a single 9 mm hole with screw fixing.

Switching Performance

Arcing time runs 10-15 ms. Maximum switching rates vary by duty: 800 cycles/hour at AC-1 (resistive), 750 at AC-3 (motor starting), 300 at AC-2 (slip-ring motors), and 130 at AC-4 (plugging/reversing). The AC-3e rating also lists 750 cycles/hour.

Frequently asked questions

Where can I buy 3RT1056-6PP35 and how do I get a price?

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

What is 3RT1056-6PP35's listed depth?

The depth is 170 mm, with a height of 172 mm and width of 140 mm.

What conductor sizes does the main power circuit accept?

The main power terminals accept stranded conductors from 25 to 120 mm² through a single 9 mm hole with screw fixing.

Will 3RT1056-6PP35 drop into a panel specified around 3RT1055-6QF35?

Both are SIRIUS S6-frame contactors with similar mounting dimensions and clearance requirements, so mechanical fit should be the same. Verify the coil voltage — the 3RT1056-6PP35 uses a 200-277 V AC coil — and confirm the auxiliary contact configuration matches your control circuit.
