7P SERIES Surge Protection Device (SPD) 7P SERIES SURGE VOLTAGE PROTECTORS Surge voltage protectors (such as Finder’s Surge Protection Devices, SPD) are intended to be installed in electrical systems, to protect people and machines from surge voltages that can occur on the electrical supply line and which would otherwise have disastrous consequences.
7P SERIES 7P SERIES Surge Protection Device (SPD) Rated values and marking common to all SPD [UC] Maximum continuous operating voltage: Under this voltage the SPD is guaranteed to appear as an “open switch”. This voltage is normally at least equal to the nominal supply voltage (UN) +10%. For the Finder SPD, UC is specified as 275 V. [Up] Voltage protection level: This is the highest voltage level seen across the SPD during its intervention.
7P SERIES Surge Protection Device (SPD) Short-circuit protection for the SPD is provided by the overcurrent protective devices (fuses type gL/gG) recomended. If the overcurrent protective devices F1 (which are part of the installation) have a rating smaller than or equal to the maximum recommended rating for the overcurrent protective devices for the SPD, then F2 (back up fuse), can be omitted.
7P SERIES 7P SERIES Surge Protection Device (SPD) PROTECTING PHOTOVOLTAIC (PV) SYSTEMS AGAINST LIGHTNING Installation characteristics [UOCSTC] PV voltage: Open circuit voltage, measured under standardized test conditions, of the PV module, panel, array, or the DC side of the photovoltaic inverter. prEN 50539-12. [ISCSTC]: Short-circuit current: Short-circuit current, measured under standardized test conditions, of the PV module, panel, array, or photovoltaic inverter. prEN 50539-12.
7P SERIES Surge Protection Device (SPD) 7P SERIES SPD fuse protection Conforming to prEN 50539-11:2010, Finder SPDs are equipped with a thermal disconnector able to safely disconnect a worn or damaged varistor up to a value of short-circuit current equal to the short-circuit current withstand value (Iscpv), as specified in the technical data. Ensure that the PV short circuit current Isc < Iscpv. Ensure that the PV short circuit current Isc < Iscpv or increase the number of the strings.
