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: Why do DC fuses need a fuse holder?

• Electrical Connection: A fuse holder is designed to securely hold the DC fuse and provide electrical connections to the circuit. It has terminals or connectors that allow the fuse to be properly connected in series with the circuit it is protecting. The fuse holder ensures a secure and reliable electrical connection between the fuse and the circuit, preventing any loose or intermittent connections that could affect the fuse's performance or compromise the safety of the system.
• Safe Handling and Installation: DC fuses often operate at higher voltages and currents, which can pose risks during installation or replacement. The fuse holder provides a protective enclosure for the fuse, preventing accidental contact with live parts and minimizing the risk of electrical shock or short circuits. It also facilitates easy installation and replacement of the fuse, allowing for safe handling without exposing the user to electrical hazards. The fuse holder typically features such as finger-safe designs, covers, and locking mechanisms to ensure safe and reliable fuse installation and maintenance.
