The photovoltaic direct current solder is a core component designed specifically for photovoltaic systems to protect high-voltage direct current overflow. It is suitable for photovoltaic array 1000V/1500V DC main current high-voltage direct current conditions. The core solves arc suppression and precision protection issues in special scenarios such as zero point, reverse current, and lightning wave surge in photovoltaic systems. It is widely installed in photovoltaic convergence boxes, photovoltaic distribution cabinets, and inverter input/output ends. It protects photovoltaic component chains, convergence circuits, and electrical and electronic devices from overload and short circuit failure damage. It is a necessary protective device for the safe operation of photovoltaic systems. It complies with international standards for photovoltaic-specific solders such as IEC 60269-6 and UL 248-17.

Features

• Compact and durable design, suitable for dense installation in electrical cabinets
• Easy-to-operate blue handle for fuse replacement
• High insulation and voltage resistance, adapted to DC 1000V PV system requirements
• Clear warning markings and standard wiring terminals for safe operation
• Comply with international safety standards, stable and reliable performance

Operation & Maintenance

• Normal Operation: The fuse holder works stably under rated voltage and current. The built-in fuse will melt automatically in case of overcurrent or short circuit, cutting off the circuit to protect equipment.
• Fuse Replacement:
  1. Cut off all power supplies connected to the fuse holder (strictly prohibit Don’t open under load).
  2. Open the blue handle, take out the melted fuse.
  3. Install a new fuse of the same specification (do not use fuses with different rated parameters).
  4. Close the handle and restore power after confirming the circuit fault is eliminated.
• Regular Inspection: Regularly check the fuse holder for damage, loose terminals, or abnormal heating; replace damaged parts in time.

Safety Precautions

• Strictly prohibit opening the fuse holder under load (Don’t open under load) to prevent electric arc, electric shock, or fire hazards.
• Do not use the product beyond the rated voltage (DC 1000V) and rated current (32A).
• Only use PV fuses matching the specifications of this fuse holder; do not replace fuses with wires or metal sheets.
• Installation, operation, and maintenance must be carried out by professional electricians in compliance with local electrical safety regulations.
• Keep the product away from moisture, dust, and corrosive environments to ensure insulation performance.
• If the fuse holder is damaged, stop using it immediately and replace it with a genuine LVMA accessory.
