DC NH Blade Fuse – 100A / 125A / 160A, 12–1000VDC for Battery & Inverter Protection
Product Overview
This DC NH blade fuse is designed for the critical DC link between battery banks and inverters. With a wide rated voltage range of 12–1000VDC and current ratings of 100A, 125A, and 160A, it provides reliable short-circuit and overcurrent protection in energy storage, solar, UPS, telecom, marine, RV, and industrial DC systems.
The NH knife-blade construction allows direct mounting in standard NH fuse bases and holders, making it an ideal replacement or OEM solution for DC distribution cabinets, battery disconnect boxes, and inverter input protection
