Product details

The Siemens 3RT1054-6QF35 is a SIRIUS power contactor in Size S6, rated for 160 A at 24 V in AC-1 duty — that's the resistive load curve, so it handles heater banks and lighting contactor panels as well as motor switching. The coil pulls 96... 127 V AC/DC (pickup at 0.8 x rated, dropout below that), and the screw-type terminals on the magnet coil accept solid conductors from 2x 0.5 mm² up to max 2x 4 mm². Main power terminals take stranded 25... 120 mm² — sized for the full 160 A path without parallel runs.

Mounts by screw fixing (no DIN-rail clip on this frame). The enclosure is 172 mm high × 140 mm wide × 170 mm deep. IP00 on the terminals; IP20 on the front with the cover or box terminal fitted — so it needs a clean, dry enclosure, not a washdown zone.

Switching performance and auxiliary contacts

Arcing time 10... 15 ms; opening time at AC and DC both 80... 90 ms.

Frequently asked questions

What is the coil voltage for 3RT1054-6QF35?

The coil is rated 96... 127 V AC/DC, with pickup at 0.8 x rated value and dropout below that threshold.

Will 3RT1054-6QF35 drop into a panel wired for 3RT1054-6QP35?

Both are Size S6 SIRIUS power contactors with the same footprint and screw-fixing pattern, so the mechanical fit and main power terminal positions are identical. The difference is the coil voltage — the 6QF35 uses 96-127 V AC/DC, while the 6QP35 uses a different coil voltage. Verify the coil supply before swapping.
