Barrier Block, 14 Circuits, 0.375" Pitch
The Molex Beau 38770 387700114 is a 14-circuit dual-row barrier terminal block with a 0.375" (9.53 mm) pitch, built for chassis or panel mounting. It uses screw top termination with a closed bottom — each wire gets its own screw clamp, and the closed back keeps terminals isolated from the mounting surface.
What the 15 A / 300 V Rating Means for the Fit
The 15 A per-circuit rating is continuous at the terminal — each screw clamp can carry that current through 14-22 AWG wire without exceeding the temperature rise of the PBT insulation.
This block mounts to a chassis or panel via the integral flanges — no DIN rail adapter, so plan for screw holes in the enclosure. The screw top termination accepts 14-22 AWG wire; the terminal screw is steel with a zinc clear chromate finish. The closed bottom means the screw terminals are not accessible from the underside — all wiring is done from the top side. The dual-wall barrier provides physical isolation between adjacent terminals, reducing the chance of accidental shorting during servicing.
