Product Description
The Mersen MPDB69122 (formerly Ferraz Shawmut) is a robust, open-style power distribution block designed for high-amperage industrial applications. This 2-pole unit is engineered for splicing large cables or splitting primary power into multiple secondary circuits, providing a secure and organized junction point for feeder and branch circuits.
Constructed with glass-filled polycarbonate for extreme durability and featuring tin-plated aluminum connectors, this block is CU9AL dual-rated for use with both copper and aluminum conductors. Its high SCCR rating and 1000V capacity make it a reliable choice for solar arrays, battery storage systems, and large-scale industrial machinery.
