Mersen’s range of 1500VDC photovoltaic (PV) fuse series is designed specifically to meet higher amperage demands of today’s PV circuits. Mersen’s 20x65mm form factor is designed to handle the harsh cyclical loads and thermal conditions of our customers’ highest amperage applications. These 1500VDC rated fuses are designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, which allows for safe circuit interruption under typical low fault current conditions. In addition to the standard ferrule terminal, fuses are also available with Crimp Cap terminals for in-line fuse applications. The unique wire crimp terminal (CC option) permits solderless wire-to-fuse connection for overmold encapsulation of fuse and wiring. Protect your off-grid or grid tied PV system from unexpected line faults using Mersen’s HelioProtection® fuse line.

Mersen offers a line of reliable UL508 and UL98 fused and non-fused disconnect switches.
