Barrier Block for Panel-Mount Power Distribution
The 387203204: The dual-wall barrier construction (2 Wall) isolates each terminal position, preventing accidental shorts from stray wire strands. The flanged mounting base secures the block to a panel or chassis with two screws, giving mechanical stability during wiring and in service. Top termination uses captive screws with a zinc clear chromate finish over steel; the bottom termination is a solder turret, insulated from the housing. Wire range accepted is 14-22 AWG, which covers the common power and control circuit sizes in panel builds. The block ships in bulk packaging.
Position Count Comparison with Siblings
The 387203204 carries 4 circuits. If the BOM calls for more positions, the same Beau 38720 series offers 5-circuit (387203205), 6-circuit (387203206), and 7-circuit (387203207) variants at the same 0.375" pitch, 15A, 300V rating, and flanged chassis-mount footprint.
