Used in new electrical installations or as replacements for blown fuses while protecting against overcurrent. Contain a metal strip / wire that melts to disconnect the circuit on exposing to greater current loads. Selected models offer bolt-in mounting for quick connection / disconnection.
Mersen HelioProtection Series HP10M fuses are ideal in electrical systems for protection against overcurrent conditions and are used in PV string / array level protection, in-line PV module, inverters and battery charge controllers. They offer a minimum breaking capacity of 1.35 times the fuse's rated current value, ensuring a reliable operation in fault currents. These enhanced fuses are ideal for constant temperature and current cycles, ensuring the longevity of the fuse and its ability to withstand repeated temperature and current fluctuations.
