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.","metaTitle":"Molex Beau 38780 387800102, 2-Circuit Barrier Block, 0.438\" Pitch","metaDescription":"Molex Beau 38780 387800102 barrier block, 2 circuits, 0.438\" (11.12 mm) pitch, 15 A, 300 V, screw top, chassis/panel mount, UL94 V-0, ROHS3.
