3-Circuit Barrier Block, 25 A at 300 V — 0.375" Pitch
The 6PCV-03-007 is a 3-circuit barrier block from the Buchanan #6 series, designed for power distribution and control wiring where a screw-terminated, through-hole mounted strip is needed. It carries a 25 A current rating at 300 V, with a 0.375" (9.53 mm) pitch that spaces the three positions wide enough for 12 AWG wire without crowding adjacent terminals. The tri-barrier (3 Wall) design isolates each circuit with a full wall on three sides, reducing the chance of a wire strand bridging to the next terminal during termination.
25 A per Circuit — Sized for Power, Not Signal
25 A per circuit on a 3-position block means each terminal is rated to carry the full current of a 12 AWG branch circuit at 105°C. That rating is the limiting factor in the wire-to-board junction — the screw clamp and PC pin are sized to handle the temperature rise at 25 A continuous without degrading the thermoplastic housing. For a 3-circuit block, the total current through the strip is 25 A per position, not a shared sum; each circuit is independent. The 300 V rating and 0.375" pitch together provide enough creepage distance between adjacent terminals for the voltage class, so the block can be used in 120/240 VAC control panels and 300 VDC power supplies without tracking across the insulation surface.
Screw Termination, PC Pin — Board-Mount Power Distribution
Top termination is a screw clamp — strip the wire, insert into the entry, tighten the steel screw. The zinc clear chromate finish on the screw resists corrosion in indoor industrial environments. The tri-barrier walls around each terminal mean a screwdriver slipped during termination won't short to the next circuit — the wall is a physical stop. For field wiring, the screw clamp accepts solid and stranded wire; the 12-22 AWG range covers most panel internal wiring from 12 AWG power feeds down to 22 AWG control signals.
Comparison with 6PCV-03-006 and 6PCV-03-009
The 6PCV-03-006 shares the same 3-circuit count, 0.375" pitch, 25 A rating, and PC pin termination — it is electrically identical. The difference is the 6PCV-03-009 and 6PCV-03-008 add a flange for chassis or panel mounting alongside the through-hole pins, which changes the mounting method from PCB-only to panel-plus-PCB. If you need the block to bolt to a panel for mechanical support before soldering, the -009 or -008 is the flange variant. The -007 is the plain PCB-mount version without the flange.
