3M Female Disconnects 14-16 AWG 25-Pack

These 3M female disconnect terminals accept 14 to 16 AWG wire and feature a 0.25 inch tab width. The blue nylon insulation provides full coverage and meets a 221 degree F maximum operating temperature. They are UL Listed and CSA Certified for 600 volt applications.

Crimp Termination with Butted Seam

Each terminal uses a crimp termination style and a butted seam construction with tin-finished brass contacts. The package contains 25 pieces for multiple wiring connections. RoHS compliant materials meet current environmental standards for electrical components.

Verify Wire Gauge and Tab Dimensions

Confirm your wire falls within the 14 to 16 AWG range before ordering. Check that the mating tab measures 0.25 inch wide by 0.032 inch thick for proper fit. Ensure the 600 volt rating matches your circuit requirements.

Questions about this item

How often will the crimp joints on these 14-16 AWG disconnects need re-crimping or replacement?

The butted-seam brass terminals with tin finish are designed for a permanent crimp; no scheduled re-crimping or replacement is required if installed correctly.

What is the first limit reached when these 0.25 in tab disconnects carry continuous current at 600 V?

The 221 °F maximum operating temperature of the nylon insulation is the primary thermal limit under sustained load.

How much heat do the blue nylon-insulated terminals generate during all-day operation?

Heat rise depends on the actual current carried; the nylon housing is rated to 221 °F and the tin-plated brass tabs minimise resistive loss.
