Product details

Motor switching capability at 480 V

The AC-3 rating governs motor starting and running — the contactor must interrupt locked-rotor current during starting, and 27 A at 480 V gives a solid margin for a 15 hp motor at that voltage.

Integration notes

Screw-type terminals for the magnet coil and main contacts accept solid or stranded wire from 1 to 10 mm², with dual-wire capability for 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Minimum clearance at the side is 6 mm; upward, downward, and forward clearance is 10 mm.

Frequently asked questions

What is the closest functional second-source for 3RT2027-1AV00?

The closest functional peer is the 3RT2016-1AG62, which shares the same S0 frame size and screw-terminal design, but the 3RT2027-1AV00 carries a higher AC-3 current rating at 480 V (27 A vs. the 3RT2016's lower rating). Panel drop-in depends on the specific load current; verify the existing contactor's rating before substituting.

Where can I buy 3RT2027-1AV00?

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

What is the depth of 3RT2027-1AV00?

The depth is 97 mm, with a width of 45 mm and height of 85 mm, fitting standard panel depths.

What wire sizes does 3RT2027-1AV00 accept?

Solid or stranded wire from 1 to 10 mm² for main contacts, with dual-wire capability for 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).
