Monitoring Relays Surge Arresters forPV system Type DSF D • Type 2 (class C) according to EN61643-11 (VDE 0675, part 6-11) • Approved UL1449 3rdEdition • Complies with IEC-61643-1, VTE C 61-740-51 • Do not require backup fuse up to 200kArms (UL 1449 3rd Ed.) • Innovative tecnology to prevent dangerous failures in case of temporary overvoltages • Suitable for unstable networks where sustainend over- voltages may persist for some minutes or longer • Plug-in cartridges • Optical indication of exhausted cartridges (red window) • Voltage-free contact, for remote function monitoring • Including thermal and dynamic separating device • Assembled unit ready for mounting • Marked connections • For DIN-rail mounting Product DescriptionOrdering Key DSF 53 C D 1200 PV DSF D is a Type 2 (Class C) surge arrester accordingto EN 61643-11 (VDE 0675, part 6-11) and UL1449 3rd edition suitable for protect- ingDC systemsfromtran- sient overvoltage due to both indirect atmospheric discharges and switching actions. It is available both in 2-pole or3-poleconfigurations, allowing both differential and common mode protection. The control windows (no/red indication)andthecontact allowbothalocalanda remote monitoring of the status of the plug-in car- tridges,warning the opera- tor about the need to promptly replace the car- tridges themselves. In installation withoutexter- nal LPS (Lightning Protec- tion System) or where the distance between the LPS elements and the solar panel frames is >50cm,DSF can be used in the DC side of photovoltaic generation plants, and can be installed on a DIN-rail in every com- mercially available distribu- tion box.
