Frequently Asked Questions

What is the 3M MN4-12R/SK ring terminal used for?

The 3M MN4-12R/SK is a nylon-insulated ring terminal designed for secure electrical connections in industrial control panels, power distribution, and heavy equipment. It handles 4 AWG wire and a 1/2 in stud, rated for 1,000 V. Common applications include motor connections, switchgear, and battery terminals where reliable, vibration-resistant terminations are required.

What are the specifications of the 3M MN4-12R/SK ring terminal?

The 3M MN4-12R/SK is a yellow nylon-insulated ring terminal with a 1/2 in stud size, accepting 4 AWG to 4 AWG wire. It is rated for 1,000 V maximum. The insulation provides abrasion and corrosion resistance. This terminal is part of 3M's standard ring terminal line, designed for crimp termination in industrial environments.
