Product details

Switching Ratings and Mechanical Life

Rated operational current in AC-3 is 27 A at 480 V, 60 Hz. The contactor is also rated for AC-1 (resistive) at 1000 operating cycles per hour maximum, AC-2 and AC-3 at 750 ops/h, and AC-4 at 250 ops/h. Arcing time is 10 ms, with a range of 4 to 16 ms at AC.

Terminal Capacity and Auxiliary Contacts

Auxiliary contact terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. The auxiliary switch is rated for 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 2 A at 500 V.

The contactor is designed for use in industrial control panels, typically switching motor loads such as pumps, conveyors, and fans.

Frequently asked questions

Where can I buy 3RT2027-1AT60-0UA0 and how do I get a price?

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

Will 3RT2027-1AT60-0UA0 drop into a panel that was specified around 3RT2016-1AG62 without rewiring?

Both are SIRIUS size S0 contactors with screw-type terminals and snap-on DIN rail mounting, so the physical footprint and mounting are identical. However, the 3RT2027-1AT60-0UA0 carries a higher AC-3 rating (27 A at 480 V) compared to the 3RT2016-1AG62, so verify the coil voltage and load current match your application before substitution.

What is 3RT2027-1AT60-0UA0's listed depth (97 mm) on this component line?

The depth is 97 mm, which is the dimension from the DIN rail mounting surface to the front of the contactor body.

What is 3RT2027-1AT60-0UA0's listed solid (1... 10 mm²) on this component line?

The main terminals accept solid conductors from 1 to 10 mm².
