They are also designed for PV applications. Their multicomponent construction provides protection against fast overvoltage transients and voltage surges, as well as long duration overvoltages. The contact provides remote indication of fault.

It is available both in 2-pole or 3-pole configurations, allowing both differential and common mode protection. The control windows (no/red indication) and the contact allow both a local and a remote monitoring of the status of the plug-in cartridges, warning the operator about the need to promptly replace the cartridges themselves.

In installation without external LPS (Lightning Protection 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 commercially available distribution box.

Features

• Type 2 (class C) according to EN61643-11 (VDE 0675, part 6-11)

• Approved UL1449 3rd Edition

• 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 overvoltages 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
