Product details

Part identity and deployment

Coil and switching behaviour

Coil pickup and dropout times are identical for AC and DC: 38-57 ms for closing, with an arcing time of 10-20 ms. Holding power at 50/60 Hz is 3.5 VA.

Main power terminals accept stranded conductors from 6 to 70 mm² — that covers motor feeds up to roughly 50-60 A depending on duty. Auxiliary and coil terminals accept solid or stranded wire: 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²). The auxiliary switch is present on this variant, so you get at least one N.O./N.C. set for feedback or interlocking.

Frequently asked questions

What is the coil voltage range for 3RT2346-1NP30-4AA0?

The coil is rated 175-280 V AC/DC, so it accepts both AC and DC control signals across that range.

What mounting options does this contactor support?

It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and can be rotated +/-180° on a vertical surface or tilted +/-22.5° forward/backward.

Where can I buy 3RT2346-1NP30-4AA0 and how is it quoted?

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