SITOR fuse link, with slotted blade contacts, NH3, In: 500 A, aR, Un AC: 1000 V, Un DC: 440 V, front indicator Fuses for stringent requirements in photovoltaic applications. Siemens photovoltaic fuses are especially designed for protecting PV modules and ensure a high level of plant availability over the entire life of the PV system. The fuses have a high DC rated voltage and withstand the greatest temperature fluctuations without damage. All Siemens photovoltaic fuse systems therefore comply with the standard IEC 60269-6.
Features
- Reliable protection of the modules and the module connection cables in the event of reverse currents
- Compliance with the UL standard UL 2579 (for IEC cylindrical fuses)
- Safe tripping in case of residual currents and therefore reduction of the risk of fire due to DC electric arcs
- Safe separation when the fuse holder/fuse base is open
- Long service life despite frequent and very variable load currents
