Bussmann 16371-3 Power Distribution Block

The Bussmann 16371-3 Power Distribution Block is a 3-pole barrier-style terminal block rated for 310 A and 600 VAC / 600 VDC, designed to safely distribute high-current power from a single source to multiple branch circuits. It provides 1 primary connection and 9 secondary connections per pole with a line-side range of 6 AWG to 350 kcmil Cu/Al, making it suitable for distribution in switchgear, motor control centers, industrial control panels, and OEM electrical assemblies. Built with tin-plated aluminum connectors and a molded thermoplastic base, the block is panel-mount and finished in black, and it carries UL Listed / Recognized design and a 100 kAIC SCCR for high fault-current conditions. Common replacements include 16372-3, 16370-3, and 16323-3, reflecting its role in legacy and new installations within industrial automation and heavy-duty power distribution. Part of the 163 Magnum series from Bussmann (Eaton Bussmann Series), this block is commonly used by maintenance electricians and system integrators for repair, retrofit, expansion, or replacement to maintain safe and efficient electrical system operation.
