Description
The Mersen MPDB67513 is a 3-pole open-style power distribution block designed for secure power splicing and branch circuit distribution in industrial control panels. Rated for 1000 VAC/VDC, it features tin-plated aluminum connectors accommodating aluminum wiring up to 270A and copper wiring up to 350A.
Part of Mersen’s intermediate MPDB series, this 3-pole block includes 2 primary box openings (wire range 2/0 to #14) and 6 secondary box openings per pole (wire range #2 to #14). Built with a durable glass-filled polycarbonate body, it measures 5.28″ wide, 3.08″ long, and 3.25″ high (134.1 x 78.2 x 82.6 mm) and supports direct screw mounting.
Key Features
- Dual Ampacity Rating: Rated up to 270A with aluminum conductors and 350A with copper conductors for flexible system design.
- 1000V AC/DC Insulation: Engineered to meet rigorous high-voltage requirements for modern industrial power distribution.
- 3-Pole Distribution Layout: Configured with 2 primary inputs and 6 secondary output openings per pole utilizing reliable box-type connections.
- High Short-Circuit Withstand: Achieves up to 100 kA SCCR when paired with appropriate upstream UL-classified fuses (Classes CC, J, L, RK1, RK5, T, and G).
- Robust Construction: Molded from high-dielectric glass-filled polycarbonate with tin-plated aluminum terminals for superior corrosion resistance and thermal stability.
