Mersen HP6M photovoltaic (PV) fuse series was engineered and designed specifically for the protection of photovoltaic systems. Its enhanced fuse construction makes it ideal for constant temperature and current cycling withstand adding to system longevity. The 600VDC rated HP6M, designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays. Protect your off-grid or grid tied PV system from unexpected ground faults and line faults using Mersen's HelioProtection fuse line.

• Low fault current interrupting capability
• Durable construction for enhanced system longevity
• Temperature cycle withstand capability
• Guaranteed operation at temperature extremes
• Industry’s first UL Listed Solution
• Globally accepted
