Product details

S3 frame contactor for motor switching in control panels

The 3RT2446-1NF30: Its AC/DC coil accepts 83...155 V, covering 110 V and 120 V nominal control supplies without needing separate coil variants — a single part number simplifies BOM management across mixed-voltage installations.

Panel fit and wiring capacity

This lets the panel builder orient the contactor to fit cable entry or busbar routing without custom brackets. Dimensions are 152 mm depth x 70 mm width x 140 mm height. The main power circuit accepts stranded wire 6...70 mm², covering motor feed cables up to the S3 frame rating. An auxiliary switch is included, reducing external component count for feedback or interlock circuits.

Frequently asked questions

What wire sizes does the main power circuit accept?

The main power terminals accept stranded wire from 6 mm² up to 70 mm².
