Product details

Motor duty and coordination

Rated for AC-2 duty at 5.5 kW on 400 V, this contactor handles slip-ring motor reversing and plugging. For AC-4 (inching, plugging, jogging) it carries 8.5 A at 400 V. Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse.

Main contacts accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x 4 mm² max. Auxiliary terminals match. AWG equivalents: 2x (20 to 16) solid, 2x (18 to 14) stranded, or 1x 12. Side-by-side mounting is supported without derating — zero gap between units on the rail.

Sourcing note

This is a standard fast mover in the SIRIUS line — keep it on the shelf if you maintain panels with 24 V DC control.

Frequently asked questions

What is the closest functional second-source for 3RT1017-1VB42?

The 3RT1016-1BB42 is a smaller-frame sibling (Size S0 vs S00) with a different coil voltage — it won't drop in without rewiring. The 3RT1017-1AD02 shares the same frame but uses an AC coil. For a direct 24 V DC replacement in Size S00, this is the part.

What compliance documentation does this brand provide for 3RT1017-1VB42?

RoHS compliance is confirmed with a substance prohibition date of 01 July 2006. The part carries IP20 protection on the front and terminals, and is rated for pollution degree 3 per IEC 60947.

Where can I buy 3RT1017-1VB42?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figures are published here.
