Barrier Block for Two-Circuit Power Distribution
The Molex Beau 38780 387800102 is a 2-circuit barrier block with a 0.438" (11.12 mm) pitch, designed for chassis or panel-mounted power distribution. It carries a 15 A current rating and a 300 V voltage rating, making it a straightforward choice for splitting a single feed into two branch circuits in control cabinets, HVAC equipment, or industrial panels. The dual-wall barrier construction provides physical isolation between the two positions, and the flange feature adds a second set of mounting holes for a more rigid panel attachment.
Top termination uses steel screws with a zinc, clear chromate finish, accepting 14-22 AWG wire. The bottom is closed, so wires enter only from the top and are clamped under the screw head — no feed-through or daisy-chaining on the back side. With 4 wire entries across the 2 circuits, each circuit can accept two conductors, which is useful for looping power to a downstream device without a separate splice.
