Overview

The NSI Industries NPDB-11-350-1 Power Distribution Block is a high-integrity electrical connector engineered for reliable splicing and tapping of 1-2 primary conductors to 1-12 secondary side conductors in industrial applications. Rated for 100kA short circuit current (SCCR), this block handles 1 x 350 MCM-6 AWG line and load connections with high-conductivity 6061-T6 electro-tin plated aluminum alloy connectors, ensuring minimal voltage drop and superior thermal performance. The NPDB-11-350-1 features a single primary (line) input and up to 12 secondary (load) outputs, supporting conductor sizes from 350 MCM down to 6 AWG on the primary side and 4 AWG to 14 AWG on the secondary side. Constructed from Valox Nylon 6/6 for structural integrity and Lexan 500R Polycarbonate for impact resistance, the block includes finger-safe panels and covers to meet OSHA safety requirements. The DIN rail mountable design (35mm) incorporates a built-in locking mechanism for secure installation and easy removal, while the modular architecture allows single blocks to combine into multi-block sets for scalable power distribution. Key specifications include a maximum ampacity of 310A per pole, a voltage rating of 600V, and an operating temperature of 90°C. Typical applications include industrial control panels, motor control centers, renewable energy systems, and other high-fault environments where reliable power distribution is critical. The screw terminal connection ensures reliable mechanical and electrical integrity, with torque ratings of 375 in.lbf for primary connections and 35 in.lbf for secondary connections.
