Product details

The 24 VDC coil pulls in at 85% of rated voltage (20.4 V) and drops out at 1.85× rated (44.4 V), with a pick-up delay of 20 to 80 ms and an arcing time of 10 to 15 ms — tight enough for sequenced interlocking but not for high-speed synchronous switching. Rated switching capacity on the DC side: 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. That 10 A at 24 VDC is the headline figure — enough for a solenoid bank or a small DC motor brake in a panel. Spring-type terminals on the coil side accept 0.5 to 4 mm² solid or stranded wire, double up to 2× (0.5 to 4 mm²). The main contacts are rated for 20 to 12 A depending on duty — check the AC-1/AC-3 curves for your load.

The 45 mm width and 70 mm height fit the S00 footprint — standard for a compact control cabinet. Depth is 73 mm including terminals. Mechanical operating rate varies by duty: up to 1,000 cycles/hour at AC-1, 750 at AC-2 and AC-3, 250 at AC-4. The AC-3e rating also maxes at 750 cycles/hour.

No auxiliary switch block is included (Auxiliary Switch: No). If you need feedback contacts, order the separate SIRIUS auxiliary switch block for the S00 frame.

Frequently asked questions

Where can I buy 3RT2017-2VB42 and how do I get a price?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is 3RT2017-2VB42's listed depth?

73 mm, measured from the DIN rail mounting surface to the front of the terminals.

What wire sizes does the spring terminal accept?

Solid or stranded wire from 0.5 to 4 mm², and up to 2× (0.5 to 4 mm²) per terminal.

Will 3RT2017-2VB42 drop into a panel specified for 3RT2015-2SB41?

Both are S00 frame contactors with the same 45 mm width, 70 mm height, and DIN rail mounting. The 3RT2017-2VB42 uses spring-type terminals while 3RT2015-2SB41 uses screw terminals — wiring method differs, but the footprint and panel cutout are identical.
