Product details

What this SIRIUS contactor brings to the panel

The 24 VDC coil pulls in at 80% of rated voltage and holds reliably across the -25 to +60 °C operating range. Screw-type terminals on both coil and main contacts accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capacity up to 2x 2.5 mm². Switching frequency tops out at 1,000 cycles per hour for resistive loads (AC-1), 750 cycles/h for motor starting (AC-3), and 250 cycles/h for plugging or inching (AC-4).

Dimensions, clearances, and mounting flexibility

Minimum air clearances: 10 mm upward and forward, 10 mm downward, 6 mm to the side. This helps when routing cables in crowded enclosures.

The 3RT2017-1FB44-3MA0 is listed as current production.

Frequently asked questions

What is the depth of 3RT2017-1FB44-3MA0?

The depth is 117 mm, with a width of 45 mm and height of 58 mm — a compact S00 footprint.

What wire sizes does the screw terminal accept?

Solid or stranded wire from 0.5 to 4 mm², and dual-wire combinations like 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm².

Will 3RT2017-1FB44-3MA0 drop into a panel specified around 3RT2016-1AG62?

Both are Size S00 contactors with the same DIN-rail footprint and screw-terminal wiring, so mechanical fit is identical. The difference is the coil voltage — 24 VDC on this part versus the 3RT2016-1AG62's coil. Verify the control voltage before swapping.
