Product details

SIRIUS S3 power contactor — 96 A at 480 V, screw terminals

The Siemens SIRIUS 3RT2046-1AH00 is a size S3 power contactor rated for 96 A at 480 V in AC-3 duty, making it suitable for switching three-phase motor loads up to that current in industrial control panels. Coil termination uses screw-type terminals; the same terminal type is used for power and auxiliary connections.

Fastens via screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715, with a width of 70 mm, height 140 mm, and depth 152 mm — fits standard panel layouts.

Duty ratings and switching frequency

Switching frequency varies by duty: AC-1 (resistive) max 900 cycles/hour, AC-2 (slip-ring motor) max 350, AC-3 (squirrel-cage motor) max 850, AC-3e (enhanced) also 850, AC-4 (plugging/inching) max 250 cycles/hour. Arcing time is 10–20 ms; operate time at AC is 10–21 ms.

Lifecycle stage is current. Mechanical life typical 10 million operations. Wire range: solid 2.5–16 mm², stranded 6–70 mm²; auxiliary contacts accept 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²).

Frequently asked questions

What is the closest functional second-source to 3RT2046-1AH00?

The 3RT2037-1AL20-ZX95 is a smaller SIRIUS contactor; it will not drop into the same panel without rewiring because the S3 frame (70 mm wide, 152 mm deep) differs from the smaller S2 frame.

What compliance documentation does this contactor carry?

The product is designed to meet IEC/EN 60947-4-1 and UL/CSA standards for contactors; documentation includes RoHS and REACH declarations from Siemens.
