Siemens 3NE43346B Fuse holder inset Suitable for PV fuse 500 A 800 V 3 pc(s)

SITOR fuse insert, with internal thread on both sides, in: 500 A, AR, UN AC: 800 V, UN DC: 440 V, front-end indicator fuses for the high requirements in photovoltaic applications. Siemens photovoltaic fuses are specially designed for the protection of PV modules and ensure high plant availability over the entire service life of the PV system. The fuses have a high DC rated voltage and withstand the highest temperature fluctuations without any damage. All Siemens photovoltaic fuse systems thus comply with the IEC 60269-6 standard. The photovoltaic fuses are characterized above all by: 1. Reliable protection of the modules and the module connection lines in case of return currents. 2. Compliance with UL standard UL 2579 (for IEC cylinder fuses). 3. A safe shutdown in case of fault currents and thus the reduction of the fire hazard by DC arcs. 4. A safe separation when the fuse holder/fuse base is open. 5. Long service life despite frequent and strongly changing load currents.
