Overview

The Mersen J300112 Protistor® fuse-link, SKU J300112, is a Size 30, aR rated high-speed fuse engineered for precise semiconductor protection in industrial power systems. This fuse operates at 690VAC according to IEC standards and 700VAC under UL specifications, with a substantial 160A interrupting rating. Its square body design features DIN 80 blades, ensuring compatibility with global mounting standards and facilitating integration into various equipment designs. The Protistor® series is renowned for its advanced construction, utilizing die-cut fuse elements embedded in solidified sand to optimize arcing characteristics. This design significantly reduces I²t values, thereby minimizing stress on protected components and enhancing overall system reliability. All contact surfaces are silver-plated to ensure low resistance and superior electrical conductivity, while non-magnetic hardware is employed to prevent any potential interference with the fuse's operation. For enhanced system monitoring, the Mersen J300112 offers optional low-voltage trip indicators that activate a microswitch, enabling remote fault signaling. This fuse is available in multiple body sizes and mounting styles, providing flexibility for diverse equipment configurations. It meets stringent IEC 700VAC and UL 160A standards, making it a reliable choice for safeguarding power conversion equipment, motor drives, and other sensitive electronic apparatus. The UNSPSC code for this product is 39121628, and it is manufactured in the US.
