What This 4-Circuit Barrier Strip Is
The Buchanan 6PCR-04-008 is a 4-circuit barrier strip from the #6 series, built for panel and chassis-mount power distribution. It uses a 0.375" (9.53mm) pitch between terminals — that spacing gives enough creepage for the 300V rating without tracking across in a damp cabinet. The three-wall (tri) barrier design isolates each circuit, so a stray screwdriver bridging two terminals is less likely. Rated 25A per circuit, it handles motor branch circuits, lighting panel takeoffs, and control transformer secondaries where a ring lug under a screw is the standard termination.
Accepts 12-22 AWG.
Operating temperature is 105°C — that's the wire rating limit, not the strip itself; derate the 25A if you're running in a hot cabinet. The housing is black, a single row, with 4 wire entries matching the 4 circuits. RoHS compliant, and the lifecycle status is Active — no last-time-buy notice, no successor part number issued.
