The 0.375\" (9.53mm) pitch spaces each terminal pair wide enough for a screwdriver and a 12 AWG wire bend — this is not a high-density block; it is built for power distribution where each circuit needs tool access and clearance for the conductor. Rated 25A at 300V, it handles motor branch circuits, panel feed-throughs, and appliance power entry where a single-row layout keeps the wiring tidy. 25A per circuit is the continuous rating — that is bus-level current for a terminal block this size. The three-wall barrier (Tri) isolates each terminal from the next, so a stripped wire touching the adjacent screw body does not create a phase-to-phase short. Steel, stainless terminal screws resist corrosion in industrial cabinet atmospheres where condensation collects on the screw heads. ## Mounting and Termination Sequence Through-hole PC pins on the bottom side solder into the board — the pins anchor the block against the torque of tightening the wire screws. The top termination uses captive screws; no loose hardware to drop into the cabinet. Wire range 12-22 AWG covers most panel power wiring; 12 AWG fills the full current rating, 22 AWG for control signals.","metaTitle":"TE Connectivity 1437653-1 Barrier Strip, 6 Circuit","metaDescription":"TE Connectivity 1437653-1 #6 Buchanan barrier block, 6 circuits, 0.375\" pitch, 25A, 300V.
