Our DC Fuses are engineered for direct current (DC) protection, specifically designed to safeguard solar photovoltaic systems, battery storage units, EV charging stations, and industrial DC applications. Built with fast-acting technology and high interrupt ratings, these fuses prevent equipment damage from overcurrents, short circuits, and system faults.

SMS Engineering’s DC Fuses ensure maximum system reliability by providing safe disconnection under fault conditions — maintaining the integrity and performance of your valuable DC assets.
