Product details

The contactor measures 45 mm wide by 73 mm deep by 58 mm high, fitting standard panel layouts without crowding adjacent devices.

Coil and Contact Ratings

The magnet coil is rated 110 V and picks up at 0.8 of rated value, so it pulls in reliably at 88 V and above. Screw-type terminals on the coil accept solid or stranded wire from 0.5 to 4 mm² (single) or 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and 2x 4 mm² for paralleled conductors. The auxiliary switch is rated for 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V — covering pilot-duty and PLC-level signals across common control voltages.

Switching Frequency and Operating Conditions

Maximum switching rate depends on duty: 1,000 cycles per hour at AC-1 (resistive), 750 cycles per hour at AC-2 and AC-3 (motor starting/running), 750 at AC-3e, and 250 at AC-4 (plugging/inching).

Frequently asked questions

What are the key ratings of the 3RT2017-1BF42?

The contactor has a 110 V AC coil, Size S00 frame, screw-type terminals accepting 0.5 to 4 mm² wire, and auxiliary contact ratings from 10 A at 24 V down to 0.3 A at 220 V. Switching frequency reaches 1,000 cycles per hour at AC-1 duty.

Where can I buy the 3RT2017-1BF42?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the 3RT2017-1BF42 drop into a panel specified around the 3RT2015-1BW42?

Both are Size S00 contactors from the SIRIUS family with the same DIN-rail footprint and screw-terminal wiring, so panel layout and wiring should be compatible. Verify the coil voltage — the 3RT2017-1BF42 uses 110 V AC — and auxiliary contact configuration for your specific circuit.
