20A fuse for photovoltaic

Product Name: 20A Photovoltaic Fuse

Device Type: Fuse for protection of photovoltaic systems

Technical Features:

Electrical Specifications:

• Rated Current: 20A
• Rated Voltage: Generally 1000V DC or 1500V DC (Please check the specific rated voltage according to your application and local regulations)
• Fuse Type: Cartridge fuse, typically designed for direct current (DC) circuits

Mechanical Features:

• Type of accommodation:
  • Cylindrical or specific format cartridge for mounting in junction boxes or protection panels.
• Construction Material:
  • External container made of insulating material and resistant to high temperatures.
  • Metal alloy fuse element designed to interrupt the circuit in the event of overcurrent.
• Dimensions: Varies depending on the fuse size (e.g. 10 x 38 mm, 14 x 51 mm, etc.)

Protection Features:

• Interruption Type: Low interruption fuse, designed to interrupt the flow of current in the event of a short circuit or overload, preventing damage to system components.
• Interruption Features:
  • Ability to interrupt high short-circuit currents typical of photovoltaic systems.
  • Fast reaction time to ensure immediate circuit protection.

Regulations and Certifications:

• Compliance Regulations:
  • IEC 60269-6 (specific for photovoltaic fuses)
  • UL 248-20 or other internationally recognized quality and safety certifications.
• Environmental Certifications: Compliant with environmental regulations, such as RoHS (Restriction of Hazardous Substances).

Environmental Features:

• Operating Temperature:
  • Typically designed to operate in a range of ambient temperatures, e.g. -40°C to +85°C.
• Ingress Protection:
  • Designed to withstand outdoor environmental conditions (check IP rating if applicable).

Applications:

The 20A photovoltaic fuse is designed to protect the electrical circuits of photovoltaic systems against overcurrents and short circuits. It is commonly used in:

• Solar Panel Junction Boxes: To protect the cables and connections between the PV modules and the inverter.
• Photovoltaic inverters: To ensure the protection of the direct current circuit that connects the panels to the inverter.
• Electrical Distribution Systems: Within residential and commercial solar installations to protect high current circuits.
