The defining fit parameter is the 0.375\" (9.53 mm) pitch between circuits — wide enough to handle 12 AWG wire comfortably while keeping the overall strip length manageable for a 16-position block. Each circuit is rated 25 A at 300 V, putting this squarely in the power distribution class: it handles branch circuits, motor control feeds, and panel wiring, not signal-level connections. The three-wall (tri) barrier design physically separates each terminal position with a full-height wall on both sides and the back, reducing the chance of an accidental short between adjacent circuits during wiring or vibration. ## Termination and Wire Fit Top termination is via screw clamps — the wire is captured under a steel or stainless steel screw head, torqued down against the conductor. This is the standard field-wiring interface for barrier blocks: no crimp tool needed, just a screwdriver. The bottom termination uses PC pins that solder into a through-hole PCB, anchoring the block mechanically and electrically. The wire range accepted is 12-22 AWG, covering the most common panel and machine wiring sizes. Single-row layout with 16 wire entries, one per circuit.","metaTitle":"TE Connectivity 9-1437653-4, #6 Buchanan Barrier Strip","metaDescription":"TE Connectivity 9-1437653-4 #6 Buchanan barrier strip, 16 circuits at 0.375\" pitch, rated 25 A and 300 V.
