32V fuse, can be used in all 12V and 24V systems. One pack contains 5 fuses. Original Victron MEGA fuses can be used in all inverters. Victron MEGA fuses are high-quality marine-grade alternative products. MEGA fuses can provide circuit protection for higher amperage applications. Victron MEGA fuses are high-quality marine-grade alternative products, which are very suitable for on-board spare parts. MEGA fuses can provide circuit protection for higher amperage applications. Victron fuses are clearly marked for easy identification of the amperage. Fuse holders are used in electrical systems where the fuse will blow when the current exceeds the safety limit of the device protected by the fuse. The end user is responsible for determining the appropriate fuse size for the circuit. Generally, the size of the fuse should be approximately 1.30 times the rated power of the device protected by the fuse.
