Siemens Sentron 3NE3 NH1 Sitor Fuse

SITOR fuse, with slitted blade contacts, NH1, In: 500 A, aR, Un AC: 1000 V, Un DC: 600 V, without indicator Fuses for reverse currents in photovoltaic systems. Siemens solar fuses are specially designed to protect PV modules and ensure a high level of system availability throughout the PV system's lifetime. The fuses have a high nominal DC voltage and withstand the greatest temperature fluctuations without damage. All Siemens photovoltaic fuse systems therefore comply with standard IEC 60269-6. The solar fuses are primarily characterized by: 1. Reliable protection of modules and module connection cables in case of reverse current. 2. Adherence to the UL standard UL 2579 (for IEC cylindrical fuses). 3. Secure release in the event of fault currents and thus reduction of the risk of fire due to DC arc faults. 4. Safe separation when the fuse holder/fuse base is open. 5. Long service life despite frequent and highly variable load currents.
