3M 7100024643 Insulated Female Disconnect 22-18 Awg

Product Description

The 3M 7100024643 is an insulated female disconnect terminal designed for quick, secure electrical connections in control wiring and light-duty circuit applications. Manufactured under the 3M MVU18-250DFK series, it accepts 22-18 AWG wire and uses a butted-seam barrel construction. The female receptacle slides over a standard male tab, with engineered dents and rolled edges on the female contact providing reliable holding force without sacrificing fast disconnect capability. Licensed electricians, HVAC controls technicians, and panel wiring professionals use this terminal for clean, serviceable connections in control panels, appliance wiring, and equipment harnesses.

This disconnect terminal is suited for control circuit wiring where serviceable, tool-free connections are required. Its 22-18 AWG wire range covers common low-voltage control wire gauges used in HVAC equipment, appliance manufacturing, and light commercial electrical assemblies. The insulated sleeve protects the connection point and aids in wire-range identification during installation. Case quantity is 1,000 units per case, making it practical for production environments and service fleets that consume disconnects in volume.

Key Features

• Accepts 22-18 AWG wire for common control and low-voltage circuit wiring
• Butted-seam barrel construction on the MVU18-250DFK female disconnect
• Engineered dents and rolled edges deliver strong retention force with tool-free disconnect
• Insulated body protects the connection and assists with wire-range identification
• Sold in case quantities of 1,000 units, suitable for production and fleet use

Compatibility

Designed for use with standard 0.250-inch male tab disconnects within the 22-18 AWG wire range. Consult wiring specifications to confirm tab width and insulation clearance before installation.

Installation Notes

Installation is performed by a licensed electrician or qualified controls technician. De-energize the circuit and verify zero voltage before terminating or removing any disconnect terminal. Strip wire to the recommended length for the barrel, crimp with a calibrated ratchet crimping tool rated for the terminal series, and inspect the crimp for full barrel engagement before mating the connection. Follow applicable NEC requirements for terminal selection, wire gauge, and insulation ratings in the installation environment.
