  • TypeElectrical Connectors
  • Pack of 10 speeds up wiring jobs
  • Crimp termination on 10–12 AWG wire ensures secure connections
  • Nylon insulation rated to 194 °F protects in high-heat areas
  • Yellow colour codes 10–12 AWG circuits for quick identification
  • UL listed and RoHS compliant meets safety standards

Velvac 30487 Quick-Disconnect Wire Terminals

This pack contains ten yellow nylon-insulated quick-disconnect terminals designed for 10 to 12 AWG copper wire. Each terminal features a tin-plated copper tab measuring 0.25 inches wide by 0.032 inches thick with a brazed seam barrel. The crimp-style termination accepts wire up to a 0.142-inch barrel inside diameter and is UL Listed and RoHS compliant for industrial and automotive electrical work.

Thermal Rating and Electrical Capacity

The nylon insulation provides full coverage and is rated for a maximum operating temperature of 194 degrees Fahrenheit. These disconnects handle up to 600 volts in normal service, and the copper contact material with tin finish maintains low resistance across the connection. No active cooling or noise considerations apply to these passive components during standard operation.

Sustained Load Behaviour

Under continuous electrical load the terminals remain within their 194-degree Fahrenheit temperature limit provided the wire gauge and crimp quality meet the 10 to 12 AWG specification. The brazed seam barrel resists separation during prolonged vibration or thermal cycling, while the tin-plated copper tab resists oxidation that could increase resistance over time. Buyers needing a larger wire range or a different tab width will need a different terminal series.

Questions about this item

How do you install the Velvac 30487 quick-disconnect terminals and what step is often missed?

Strip the wire, insert it fully into the brazed barrel, and crimp with a ratchet tool sized for 10–12 AWG; the step often missed is verifying the insulation seats completely inside the nylon cover for full coverage.

What maintenance or replacement will these yellow nylon disconnects need over time?

Inspect the tin-plated copper tabs for oxidation or loose crimps after thermal cycling; replace any terminal showing discolouration, cracked nylon, or a tab that no longer grips at 0.25 in width.

What limit appears first when these connectors run continuously at high current?

The 194 °F maximum operating temperature of the nylon insulation is reached before the 600 V voltage rating or the 0.032 in tab thickness becomes a constraint.
