Applications

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 a DC fuse?

A DC fuse, also known as a direct current fuse, is a safety device designed to protect electrical circuits and equipment from excessive current flow. It is specifically used in DC (direct current) systems, which are commonly found in vehicles, solar power systems, battery banks, and other applications where DC power is utilized.

Similar to an AC (alternating current) fuse, a DC fuse consists of a thin strip or wire made of a material that has a low resistance to electrical current. When the current passing through the fuse exceeds its rated capacity, the wire inside the fuse heats up and melts, breaking the circuit and interrupting the flow of electricity. This action prevents damage to the connected equipment and helps prevent electrical fires.

DC fuses are rated for specific voltage levels and current capacities, and they come in various sizes and designs to accommodate different applications. It is important to select a fuse with the appropriate voltage and current ratings to ensure effective protection.

It's worth noting that DC fuses and AC fuses are not interchangeable. DC circuits have unique characteristics that require fuses specifically designed for direct current. Therefore, it is essential to use DC-rated fuses when working with DC systems to ensure safety and proper functionality.
