The importance of
UL 2579 – Fuses for Photovoltaic Systems
11
UL 2579 – Fuses for Photovoltaic Systems
Background Information
UL 248 – Low Voltage Fuses
– Divided into 16 sub-categories
• Class CC, Class RK, Class H, Class J, Plug Fuses, etc…
– Intended Applications
• Power Controls
• Power Low Voltage Distribution
• Power Electronics
12
UL 2579 – Fuses for Photovoltaic Systems
General Performance Characteristics
– Voltage Rating may be up to 1500VDC
– Interrupting Rating is 10kA minimum
– Classification: Non-Renewable, Not Current-Limiting
13
UL 2579 – Fuses for Photovoltaic Systems
Markings
– In addition to the marking requirements in UL 248-1, the fuse must
be marked with the letters “PV” or “gPV” or the text “Photovoltaic
Fuse”.
14
UL 2579 – Fuses for Photovoltaic Systems
Expanded tests specific to PV application
– Verification of Freedom from Unacceptable Levels of Thermally
Induced Drift
• Electrical performance verified after repeated thermal cycling
• Simulates night to day thermal climate cycle
– Verification of Functionality at Temperature Extremes
• Fuse to be conditioned at 50°C and electrically tested to verify
functionality (compared to 25°C for UL 248)
– Current Cycling
• Fuses undergo current and thermal cycling to verify life expectancy and
to prevent pre-mature fuse opening
