FDRQ100-10NB - 4/0 AWG Square Ring Terminals, 3/8" Stud, 5 pieces

SQUARE TONGUE RING TERMINALS The uniquely shaped square tongue ring terminals are an excellent solution for even the most demanding high-current applications. The innovative rectangular tongue is the key. Unlike standard round terminals that can twist and loosen under vibration, the flat edges of our square tongue lock firmly against busbars, terminal blocks, or adjacent lugs. This anti-rotation design guarantees a secure, stable connection that stays tight. This shape also maximizes the surface-to-surface contact area, providing superior electrical conductivity and improved heat dissipation for a safer, more efficient circuit.
