Siemens 3NE13343 Fuse holder inset Suitable for PV fuse Fuse size = 2 500 A 690 V 3 pc(s)

SITOR fuse link, with slotted blade contacts, NH2, In: 500 A, GR, Un AC: 690 V, head detection fuses for the high requirements in photovoltaic applications. Siemens photovoltaic fuses are specially designed to protect PV modules and ensure high plant availability over the entire life of the PV system. The fuses have a high DC rated voltage and withstand high temperature fluctuations without any damage. All Siemens photovoltaic fuse systems thus correspond to the standard IEC 60269-6. The photovoltaic fuses are characterized above all by: 1. Reliable protection of the modules and the module connection cables in case of return currents. 2. Complies with UL standard UL 2579 (for IEC cylinder fuses). 3. A safe shutdown in the event of fault currents and thus the reduction of fire hazard through DC electric arcs. 4. Safe separation when the fuse holder/fuse bottom is opened. 5. Long life despite frequent and strongly changing load currents.
