Product details

The 24 V DC coil draws 10 A at rated value, with a pick-up dropout characteristic typical of SIRIUS contactors — the initial pull-in value is 0.8, and arcing time runs 10 to 15 ms.

The contactor occupies a 45 mm wide by 58 mm high by 73 mm deep envelope. The screw-type 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), and 2x 4 mm². This fits standard panel gland plates without special adapters.

Rated operational current at AC-1 (resistive load) is 1,000 operations per hour maximum; at AC-3 (motor starting) it's 750 ops/h; at AC-4 (plugging/inching) it's 250 ops/h. The AC-3e rating also allows 750 ops/h. For DC switching at 24 V rated value, the contactor handles 10 A; at 48 V it's 2 A; at 60 V it's 2 A; at 110 V it's 1 A; at 125 V it's 0.9 A; at 220 V it's 0.3 A; at 400 V it's 3 A. The auxiliary switch is included. Mechanical life is typical 30 million operations. These ratings define the real-world duty — the AC-3 figure governs motor switching, while the DC derating curve matters for solenoid or brake loads.

Frequently asked questions

What is the depth of 3RT2017-1BB42?

The depth is 73 mm, with a width of 45 mm and height of 58 mm.

What wire sizes does the 3RT2017-1BB42 accept?

Solid or stranded wire from 0.5 to 4 mm² single, or two conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm².

Will 3RT2017-1BB42 drop into a panel specified for 3RT2036-1AC20-ZX95?

No — the 3RT2036-1AC20-ZX95 is a larger Size S2 contactor with different mounting dimensions and terminal layout. The 3RT2017-1BB42 is Size S00 and will not directly interchange without panel modifications.
