It's a through-hole board-mount block with PC pin solder tails on the bottom and screw-clamp terminals with captive plates on top. The dual-wall barrier design isolates each circuit from the next, which keeps field wiring from shorting across terminals when you're landing a screwdriver. Rated 10A at 300V, it handles the typical control-voltage and low-power distribution you see in industrial panels, HVAC controllers, and appliance PCBs. Wire gauge acceptance runs 16-30 AWG, which covers solid and stranded building wire and most equipment-level signal wiring. Terminal screw material is steel with a nickel finish, which resists corrosion in a panel environment without galling against the wire. ## Build and Environment Color is black, which is the typical Buchanan visual identifier on a panel rail.","metaTitle":"1546657-4 Buchanan Barrier Block, 4 Circuit, 0.250\" Pitch","metaDescription":"1546657-4 Buchanan barrier strip, 4 circuits, 0.250\" (6.35mm) pitch, 10A, 300V, UL94 V-0 nylon.
