Overview

The Mersen 40352G is a 2-pole Class G fuse block engineered for demanding 480VAC/VDC applications with a 30A rating. This robust unit is equipped with high-quality copper box connectors, designed to accept a broad spectrum of stranded or solid copper wire, accommodating sizes up to #6 AWG. The insulating components are fabricated from glass-filled polycarbonate (GFPC), a material that provides verified dielectric strength surpassing 2500V. These insulators also boast a temperature rating of 125°C RTI and meet the stringent 94V-0 flammability standard. Mersen Class G fuse blocks, including the 40352G, are specifically designed to house all Class G fuses ranging from 15, 20, 30, and 60 amperes. A significant design advantage is the innovative adder block capability, which enables the creation of flexible multi-pole configurations by simply snapping onto existing 1-, 2-, or 3-pole blocks. The fuse clips themselves are precision-manufactured from a high-conductivity tin-plated copper alloy, guaranteeing consistently reliable electrical contact. This fuse block adheres to UL 4248 requirements and holds UL Listing (guide IZLT, File E52283) and CSA Certification (class 6225, File 32169). It features a Short Circuit Current Rating (SCCR) of 100kA. This product is proudly made in the USA. SKU: 40352G.
