This fuse unit is rated for 14.4 kV nominal voltage and provides reliable protection for electrical circuits in outdoor applications. The 252050R4 fuse unit is compatible with SM-4 holders and is engineered for use in systems requiring a 30E amp rating. It features a slow-blow time-current curve (TCC 119-4) for optimal coordination with downstream devices. This unit is suitable for solidly grounded-neutral systems and is designed for single-conductor, concentric-neutral type cable connections to transformers.
