Product details

With a width of 45 mm and depth of 73 mm, it fits standard panel layouts. The contactor is rated for 10 A at 24 VDC and 3 A at 400 VAC, and provides 2 hp at 230 VAC — suitable for small motor and general switching duties.

The DC-13 switching ratings tell you the contactor can handle inductive DC loads: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, and 0.3 A at 220 V. This is the curve you use for solenoid valves, DC brake coils, and similar loads — the AC-1 or AC-3 ratings don't apply there. Maximum switching frequency at AC-1 is 1,000 cycles/hour, at AC-3 it's 750 cycles/hour, and at AC-4 it's 250 cycles/hour — the heavier the load, the fewer operations per hour the contactor can sustain.

Wiring and integration notes

Screw terminals accept solid or stranded wire: 0.5 to 4 mm² single, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Strip length is 10 mm for the main contacts. The coil hold-in voltage is 0.8 of rated value, with a full-scale pickup of 1.1 times rated.

Frequently asked questions

What are the key ratings for this contactor?

The contactor is rated for 10 A at 24 VDC, 2 A at 48 V and 60 VDC, 1 A at 110 VDC, and 0.3 A at 220 VDC. For AC loads, it provides 3 A at 400 VAC and 2 hp at 230 VAC. Mechanical life is 30,000,000 operations typical.

How does 3RT2017-1BM42 compare to 3RT2017-1AB01-ZX95?

Both are size S00 SIRIUS power contactors. The 1BM42 uses a 24 VDC coil; the 1AB01-ZX95 uses a different coil voltage. They share the same mounting footprint (45 mm wide, 73 mm deep, snap-on DIN rail) and terminal wiring range. Rewiring is not needed for the same load — just verify the coil voltage matches your control circuit.

What is the depth of 3RT2017-1BM42?

The depth is 73 mm.

What wire sizes does the contactor accept?

Screw terminals accept solid or stranded wire from 0.5 to 4 mm² for a single conductor, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².
