Applications

RDDLZ DC fuse with a fuse holder is specifically designed for use in solar power systems operating on direct current (DC). Its primary purpose is to provide overcurrent and short-circuit protection within the system. By interrupting the circuit when the current exceeds safe levels, the PV fuse prevents damage to solar panels, charge controllers, batteries, inverters, and other components.

Tips: Are DC and AC fuses the same?

DC fuses and AC fuses differ in their design and functionality to accommodate the distinctive characteristics of direct current (DC) and alternating current (AC) systems. DC fuses are designed to interrupt the flow of continuous current in a single direction. They utilize materials with higher melting points to effectively handle the challenges of arc extinguishing in a DC circuit. DC fuses are constructed with materials like silver, copper, or silver-plated copper to enhance arc quenching capabilities. Their design prioritizes reliable interruption of the current, ensuring safe operation in direct current systems.

In contrast, AC fuses are specifically engineered to address the periodic nature of alternating currents. AC circuits experience regular changes in current direction, with zero-crossings occurring where the current passes through zero. AC fuses are designed to take advantage of these zero-crossings for efficient arc extinguishing. They often incorporate additional features such as arc chutes or magnetic blowouts to enhance arc suppression and interruption capabilities. These elements facilitate the safe and reliable interruption of the alternating current, providing effective protection against overcurrent conditions in AC systems.
