Product details

Solistrand ring terminal for 4 AWG

The 1-331420-0 is the 4 AWG, 5/16 stud member of TE's Solistrand ring terminal line, a non-insulated circular terminal for free-hanging crimp termination. Tin-plated copper construction with a brazed seam and serrated termination — the serrations bite into the conductor strands during crimp for a gas-tight joint.

Stud size and wire gauge across the series

Within the Solistrand 4 AWG ring terminal group, the 1-331420-0 uses a 5/16 stud opening while the 1-331420-1 uses a 3/8 stud — the same 0.679" (17.25 mm) outer width and 0.091" (2.31 mm) thickness, so the board or busbar hole size is the only fit difference. For 8 AWG applications the 1-331414-1 matches the 5/16 stud but carries a narrower 0.587" (14.91 mm) outer width — the 4 AWG terminal is the wider-bodied option for the heavier cable.

Frequently asked questions

Where can I buy 1-331420-0 and how do I get a price?

The 1-331420-0 is an active TE Connectivity AMP Solistrand ring terminal. Submit an RFQ with quantity to confirm pricing and lead time.

Will 1-331420-0 drop into a panel that was specified around 1-331420-1 without rewiring?

The 1-331420-0 uses a 5/16 stud opening; the 1-331420-1 uses a 3/8 stud. Both share the same 0.679" (17.25 mm) outer width and 0.091" (2.31 mm) thickness — the stud hole on the busbar or panel must match the terminal stud size.
