Barrier Strip for Panel Wiring — 4 Circuits, 0.438" Pitch
The Molex Beau 38739 387390106 is a 4-circuit barrier strip terminal block with a dual-wall barrier design, rated 15 A at 300 V. The 0.438" (11.12 mm) pitch gives enough spacing between terminals for 14-22 AWG wire termination without crowding adjacent connections. This is the flanged chassis-mount version — the mounting ears take the mechanical load off the solder turrets when the block is bolted to a panel.
The 15 A per-circuit rating is continuous at the rated temperature — the limiting factor is the thermoplastic insulation (UL94 V-0) and the screw-clamp contact interface, not the solder turret bottom termination. The 300 V rating is the working voltage between adjacent circuits, which the 0.438" pitch supports without tracking across the barrier wall.
