Fuse Bases 600V 400A Class J 3-pole Side-Clip

Product Description

The Fuse Bases 600V 400A Class J 3-pole Side-Clip utilizes a variety of connectors including screw, pressure plate, box, and special order stud connectors, compatible with both stranded and solid copper or aluminum conductors. The insulators consist of molded glass-filled polycarbonate (GFPC) or phenolic, demonstrating verified dielectric strength exceeding 2500V.

Notably, the 30A, 60A, and 100A SJ fuse blocks incorporate a unique adder block configuration, allowing for expansion into multi-pole segmented blocks with desired pole counts. Each fuse clip is constructed from high conductivity tin-plated copper and is available in both spring-reinforced and non-spring reinforced options. Furthermore, space-saving designs are available in the 30A and 100A configurations as noted in the product selection tables.

This product has a maximum operating temperature of 80 °C and a minimum storage temperature of -25 °C, with a short circuit current rating (SCCR) of 200 kA. The torque rating stands at 375 lb-in, ensuring secure installation when mounted directly via screws. The rated voltage for both AC and DC applications is 600V, while the ampere rating aligns at 400A, making it a suitable choice for various industrial electrical systems.
