The 0.325\" (8.26 mm) pitch gives enough space between terminals to land 12 AWG stranded wire without the insulation crowding the adjacent screw. Rated 20 A per circuit at 150 V, it handles low-voltage DC power feeds or control signal pairs inside an industrial cabinet — not line-voltage mains. The dual-wall barrier isolates each circuit and stops a stray strand from shorting across to the neighbour. ## Wiring It: Screw Termination and Wire Range Top termination is a screw with a captive plate — the plate stays captured under the screw head even when fully loosened, so you don't lose it during a field rewire. Accepts 12-22 AWG solid or stranded; the steel screw with zinc clear chromate finish torques down without galling the wire. ## Where It Lives: Panel Cabinet and Temperature Range The 2-circuit format is a common fit for a single sensor power pair or an actuator return line on a DIN-rail-mounted PCB.","metaTitle":"4DB-R108-02 Barrier Block, 2 Circuits, 0.325\" Pitch, 20 A","metaDescription":"4DB-R108-02 Buchanan 4DB barrier block, 2 circuits, 0.325\" pitch, 20 A, 150 V, 12-22 AWG, screw with captive plate, UL94 V-0.
