Crimp Cap Termination for HelioProtection HP10M, HP15M, and HP15G Fuses

Mersen’s HP10M, HP15M, and HP15G HelioProtection photovoltaic fuses are engineered specifically for the protection of PV systems. Mersen’s crimp cap termination for HP10M, HP15M, and HP15G fuses enables users to attach wires directly to the fuses. This eliminates the need for a fuse holder and allows an overmolded enclosure.
