This NSi Industries IPLDH750-4 Polaris insulated connector block connects up to four cables from 750 to 250 MCM (thousand circular mils). It is made of 6061-T6 aluminum alloy for conductivity and resistance to corrosion, and insulated with plastisol for high-dielectric strength and resistance to chemicals, abrasion, and UV radiation. It is dual rated for use with both copper and aluminum cables, but is not recommended for use with fine-stranded, flexible wire and does not support combustion applications. The connector comes with removable access plugs that cover unused entry ports and 5/16" hex screws, which hold the wires in place in the block. Wire entry ports are located on both sides of the connector, and two internal pressure screws are provided for each cable for secure connections. The connector is rated for 600V and has a temperature range of -45 to +90 degrees C. It measures 6.4 x 3.5 x 4.5 inches (L x H x W), and is Underwriters Laboratories (UL) and Underwriters Laboratories of Canada (cUL) Listed. (L is length, the horizontal distance from left to right; H is height, the vertical distance from bottom to top; W is width, the horizontal distance from front to back.) This insulated connector block is suitable for a wide range of electrical applications with appropriately sized conductors.
