4-Circuit Barrier Block, 0.325" Pitch, 20 A
The TE Connectivity Buchanan 4DB-P108-04 is a 4-circuit barrier terminal strip from the 4DB series, designed for through-hole mounting with PC pin terminations on the board side. The 0.325" (8.26 mm) pitch spaces the terminals wide enough to handle 12-22 AWG wire comfortably, with the 20 A per-circuit rating driven by the screw-and-captive-plate top termination that clamps the conductor without damaging strands.
The 12-22 AWG wire range covers most panel and control-circuit wiring; the steel screw with zinc, clear chromate finish provides corrosion resistance in cabinet environments.
