Reliance RFC150 Fuse NSMP

Reliance RFC150 Fuse NSMP is a legacy Reliance Electric cartridge fuse designed to provide overcurrent protection in industrial electrical circuits. Listed with the NSMP suffix, this RFC150 variant appears in distributor catalogs as part of the Reliance Electric RFC fuse family, reflecting its use in older equipment and compatibility with related power panels, drives, and control circuits. The RFC150 designation places it in the RFC fuse family used for interrupting fault currents within electrical assemblies, and the NSMP packaging variant is seen in archival parts catalogs that service legacy Reliance/ABB equipment. As a fuse designed for protection against overcurrent, it is intended to be replaced in accordance with the original equipment manufacturer's service documentation and OEM replacement guidelines. Because this is a legacy item, confirm that the NSMP packaging matches your equipment's fuse holder style and that the fuse's ratings align with the original specification before replacement. In practice, technicians reference RFC150 NSMP when maintaining legacy Reliance Electric controls and when replacing similar RFC fuses in equipment sourced from vendors who used Reliance Electric components. These fuses are typically used in power distribution and drive systems where reliable fault-current interruption is required and where compatible cartridge-style holders are part of the equipment design.
