3M 7100024641 Insulated Butt Splice 12-10 Awg

Product Description

The 3M 7100024641 is an insulated butt splice connector designed for making secure, in-line wire terminations on copper conductors. The connector accepts wire gauges from 12 to 10 AWG and features a butted seam construction that maintains a reliable crimp profile. A rolled-edge and dented female receptacle design provides strong holding force at the disconnect interface while still allowing fast, tool-free separation when needed. Licensed electricians and industrial maintenance technicians use this type of connector for splicing conductors in control panels, equipment wiring harnesses, and general electrical assemblies.

This connector is suited for residential, commercial, and light industrial wiring applications where a clean, insulated in-line splice is required. The MVU10-250DMK designation identifies it as a disconnect-style butted seam connector with a female tongue that slips over a corresponding male tab to complete the circuit. It is packaged in case quantities of 500, making it appropriate for high-volume production or service work where consistent, repeatable terminations are critical.

Key Features

• Wire range: 12-10 AWG for mid-gauge copper conductors
• Insulated butted seam construction for reliable crimp integrity
• Rolled edges and dents on female part deliver strong retention with easy release
• Female tongue slip-over design mates securely with standard male tab disconnects
• Sold in 500-piece case quantities for production and service volume needs

Compatibility

Designed as an OEM-style replacement and standard-fit connector for 12-10 AWG insulated disconnect and butt splice applications in electrical wiring assemblies.

Installation Notes

Installation is performed by licensed electricians or qualified maintenance technicians. Always de-energize and lock out the circuit before making any wire terminations in accordance with NFPA 70 (NEC) requirements. Use a calibrated ratcheting crimp tool rated for insulated terminals to ensure a full, consistent crimp on each connector. Inspect each termination for insulation damage and verify seating before restoring power.
