Anti-overcurrent protection
Protects electrical systems from overcurrent conditions that can damage electrical components by interrupting the flow of electricity when it exceeds a certain threshold.
Specific component protection
Protect specific components, such as battery packs or electric motors, from overcurrent conditions unique to their operating requirements.
Security protection
High voltage DC fuses protect against electrical hazards and ensure the safety of the vehicle and its occupants.
Energy efficiency
Limiting current flow prevents energy from being lost as heat, which improves the vehicle's energy efficiency and extends its range.
High voltage DC fuse
High voltage DC fuses are an important component in solar and storage systems. Its main function is to provide protection by interrupting the current flow in the event of a fault, such as overcurrent or short circuit. This prevents damage to the system and ensures safe operation. High voltage DC fuses are used in photovoltaic solar systems and energy storage systems where high DC voltage and current levels are present. Its reliability, durability and high interruption capabilities make it an ideal solution for these applications. circuit when a vehicle accident occurs, preventing further discharge of the battery system and reducing the risk of safety accidents.
