3M 7000133330 Vinyl Insulated Ring Tongue Terminal

Product Description

The 3M 7000133330 is a vinyl-insulated, brazed-seam ring tongue terminal designed for secure, permanent electrical connections in building wiring, signs, fixtures, and luminaires. Built from electrolytic copper with a tin-plated finish, it delivers reliable conductivity and corrosion resistance in demanding environments. The terminal is rated for 600 volts on building wire and 1000 volts for signs, fixtures, and luminaires. It withstands a temperature range of -40 to 221 degrees F (-40 to 105 degrees C). Electricians and wiring professionals install these terminals where a locked, stud-mounted connection is required. The ring tongue style cannot be pulled free without removing the mounting screw, making it the standard choice for safety-critical terminations.

This terminal is suited for residential and commercial electrical installations wherever a ring-style lug connection is needed. The funnel-entry polyvinyl chloride sleeve simplifies wire insertion during termination. Sold in a 100-piece bottle, the MV14-38RX is a practical bulk quantity for service work, panel builds, sign installations, and fixture wiring where repeated use of the same terminal size is expected. The brazed-seam barrel construction maintains consistent grip and electrical contact across the full wire engagement zone.

Key Features

• Vinyl-insulated, brazed-seam barrel for consistent wire grip and insulation integrity
• Electrolytic copper construction with tin-plated finish for conductivity and corrosion resistance
• 600V rated for building wire; 1000V rated for signs, fixtures, and luminaires
• Temperature range: -40 to 221 degrees F (-40 to 105 degrees C)
• Funnel-entry PVC sleeve for easier wire insertion during termination
• UL Listed, CSA Certified, and RoHS 2011/65/EU Compliant

Compatibility

Designed as a standard ring tongue terminal for use in building wire applications, sign wiring, fixture wiring, and luminaire installations where a stud-mounted, screw-retained connection is required.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating any conductors. Use a calibrated ratchet crimping tool rated for insulated terminals to ensure full crimp engagement on the barrel. Do not over-strip wire insulation, as exposed conductor beyond the barrel increases the risk of contact with adjacent conductors or grounded surfaces.
