SKU CH-XWBM-RKDHY

Blue vinyl-insulated female disconnects accept 16-14 AWG wire and fit .25 inch tabs, supplied in a pack of 100

  • Product typeElectrical Connectors
  • Reliable crimp connection for 16-14 AWG wire
  • Blue vinyl insulation identifies circuit at a glance
  • Tin-plated brass tab resists corrosion over time
  • Rated 600 V and 221 °F for demanding use
  • Pack of 100 speeds large wiring jobs

16–14 AWG crimp disconnects

These blue female disconnect terminals accept 16 to 14 AWG conductors and feature a 0.25 in tab width with 0.032 in thickness. The vinyl insulation provides partial coverage and is rated to 221 °F. A pack contains one hundred pieces for volume wiring jobs.

Thermal and electrical ratings

Maximum operating temperature reaches 221 °F while the brass contacts carry up to 600 V in normal use. Tin plating on the brass resists oxidation without adding measurable resistance. The butted seam and vinyl sleeve remain stable under continuous load.

Standards and compliance benefits

UL listing and CSA certification confirm the terminals meet recognised North American safety requirements. RoHS compliance removes restricted substances for regulated projects. The UL 94 flammability rating is not applicable, simplifying material approvals.

Questions about this item

How do I crimp the 16-14 AWG wire into the blue vinyl barrel and what is the common mistake?

Strip the wire to the correct length, insert fully into the barrel, and compress with a ratchet crimp tool sized for 16-14 AWG; the frequent error is using pliers instead of a proper crimper, which leaves a loose connection.

Will the tin-plated brass tab need replacement due to corrosion or heat cycling?

The tin finish on brass resists oxidation up to the 221 °F rating; under normal voltage and temperature conditions the disconnect does not require scheduled replacement.

At what current level does the .032 in thick tab become the limiting factor during sustained load?

The .25 in wide tab rated for 600 V and 221 °F will reach its temperature limit before the crimp or insulation degrades, making thermal rise the first constraint under continuous current.
