    ATO 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: What is the purpose of a DC fuse in an electrical system?

    The purpose of a DC fuse in an electrical system is to provide protection against overcurrent conditions. DC fuses are designed to interrupt the flow of direct current when the current exceeds a safe threshold. They act as a safety device that prevents excessive current from flowing through the circuit and causing damage to the electrical components or posing fire hazards. By quickly interrupting the circuit, DC fuses help protect the system, wiring, and connected devices from the potentially harmful effects of overcurrent, ensuring the safe and reliable operation of the electrical system.
