Product details

The coil is rated for 200-277 V AC, with a pickup operating time of 80-100 ms on both AC and DC supplies. The arcing time sits at 10-15 ms. Minimum operating factor is 0.8 at 50 Hz and 0.8-1.1 at 60 Hz, so it holds in during brownout conditions down to 80% of rated voltage. Main power terminals accept stranded conductors from 70 to 240 mm² — that's the range you'd expect for a contactor this size, handling supply feeds up to several hundred amps. Auxiliary control wiring uses screw-type terminals accepting solid wire: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or max 2x (0.75-4 mm²). The auxiliary switch is present and rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — typical for signaling back to a PLC input or a status lamp.

Physical footprint: 214 mm high, 180 mm wide, 225 mm deep. That depth is the dimension you need to check against your enclosure depth — at 225 mm, it's a deep unit, so plan for cable bending radius behind it. Mounting uses one hole of 11 mm diameter. Protection degree is IP00 on the terminals and IP20 on the front with the cover or box terminal installed. Maximum switching frequencies: 500 operations/hour in AC-1 (resistive), 170 in AC-2 (slip-ring motors), 420 in AC-3 (squirrel-cage motors), and 130 in AC-4 (plugging/inching).

Frequently asked questions

What is the closest functional second-source — 3RT1076-6AP36?

The 3RT1076-6AP36 is a peer variant in the same SIRIUS S12 frame. The key difference is the coil voltage: the 6AP36 uses a different coil voltage than the 6QP35's 200-277 V AC. They share the same physical footprint and terminal ratings, so a panel designed for the 6AP36 can accept the 6QP35 without rewiring the main power or auxiliary circuits, provided the coil supply matches.

What is 3RT1076-6QP35's listed depth?

The depth is 225 mm.

What solid conductor sizes does the auxiliary terminal accept?

The auxiliary screw terminals accept solid wire: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or max 2x (0.75-4 mm²).

Will 3RT1076-6QP35 drop into a panel specified around 3RT1076-6AP36 without rewiring?

Yes, the physical dimensions and terminal ratings are identical between the two S12 frame variants. The only difference is the coil voltage, so as long as the panel's control voltage matches the 6QP35's 200-277 V AC coil, it is a direct mechanical and electrical swap.
