Mersen NH Fuses 80A to 250A DC Battery Protection

Mersen NH fuses give high current protection for deep-cycle solar batteries and inverters in off-grid and hybrid photovoltaic systems. Available in 80A, 100A, 160A, 200A and 250A ratings, they use a gR-curve ultrarapid characteristic that guards against overload conditions and offers a safe way to isolate a battery bank for maintenance or repair.

Key features of this dc surge protection device

• Ratings, 80A, 100A, 160A, 200A, 250A
• Format, NH knife-blade fuse
• Curve, gR ultrarapid, for overload and battery protection
• Battery compatibility, deep-cycle lead-acid and lithium banks
• Inverter protection, guards against battery overcurrent faults
• Junction box use, suited to high current DC array junction boxes

Applications

• Battery overcurrent protection in off-grid solar systems
• Inverter DC input protection in hybrid battery storage systems
• Level 2 array junction box protection in large solar PV installations

Installation notes

These fuses must be fitted into a correctly rated NH fuse holder or switch disconnector. DC battery circuits carry dangerous voltages and high fault currents, so installation should only be carried out by a qualified electrician.
