The terminal screw is steel with a zinc, clear chromate finish, which resists corrosion in a cabinet environment without plating flake issues. The bottom termination is closed, meaning no through-hole pins or solder tails — all connections are made at the screw terminals on top. Mounting is chassis or panel via the integral flange. The block does not snap onto DIN rail — it bolts down. That makes it a direct replacement for older barrier strips in existing panels where the hole pattern is already drilled.","metaTitle":"Molex Beau 38770 387700103 Barrier Block, 3 Circuit, 0.375\" Pitch","metaDescription":"Molex Beau 38770 387700103 barrier terminal block, 3 circuits, 0.375\" (9.53mm) pitch, 15A at 300V, screw top, chassis mount with flange, 14-22 AWG, UL94 V-0, ROHS3 compliant.
