160 A power contactor with 96-127 V coil — SIRIUS S6 frame
The 3RT1056-6QF35: This is a SIRIUS-branded power contactor in the S6 frame size, rated 160 A at 24 V (the rated operational current for the main poles). The magnet coil is screw-type terminals and accepts 96-127 V AC/DC — a common control voltage range for industrial panels running 110-120 V control transformers. The 160 A rating at 24 V is the thermal current; for motor switching duty (AC-3), the contactor handles up to 750 switching operations per hour, and for resistive loads (AC-1) up to 800 operations per hour. The arcing time sits at 10-15 ms, which is typical for a contactor of this frame size and keeps contact erosion predictable in repetitive cycling.
Termination range and panel fit — 25-120 mm² power, solid aux
The main power terminals accept stranded conductors from 25 mm² up to 120 mm² — that covers everything from a 50 mm² motor feed to a 95 mm² bus drop. The auxiliary circuit terminals handle solid wire from 0.5 mm² to 4 mm² (two conductors per clamp), which is the standard range for control wiring in a panel. Mounting is screw fixing (not DIN rail snap-on), so plan for drilled holes and a backplate. Clearances: 10 mm downward, 10 mm sideways, 20 mm forward, 10 mm upward — these are the minimum air gaps to maintain the rated thermal performance and arc-quenching. The enclosure is IP00 on the body (no protection against dust ingress on the live parts), but IP20 on the front when the supplied cover or box terminal is fitted — that is touch-safe for the operator side of the panel.
Auxiliary switch included — one less SKU to order
This contactor ships with an auxiliary switch block integrated (yes/no field confirmed as Yes). That means you do not need to order a separate side-mount aux contact for basic status feedback or interlocking — it is already on the contactor.
