DC Surge Protective Device Jean Müller C3947 Type 1+2 1000V 1 MPPT

The Jean Müller C3947 (model DS60VGPV-1000) is a surge protective device (SPD) of the combined Type 1+2 class, specific to the DC side of photovoltaic systems. It protects one MPPT with a three-pole Y structure, which discharges the three PV+ / PV− / PE paths to earth, and works up to 1000V DC (Ucpv), with a withstand of up to 1200V DC.

It is installed in the DC combiner box, as close as possible to the inverter's string input or near the photovoltaic generator, and it is the device to adopt when the building or the system is fitted with lightning protection or exposed to direct lightning strikes: the Type 1 component discharges a lightning current Iimp of 12.5kA per pole, i.e. 25kA in total with a 10/350 µs waveform, while the Type 2 function limits induced surges, with an Imax of 20kA on an 8/20 µs wave. The VG technology combines varistors and a spark gap to achieve low residual protection levels with no permanent leakage current. A red mechanical indicator shows which module needs replacing and a changeover remote signalling contact makes it possible to report the alarm at a distance, an essential function in unattended installations.

Key features

Type 1+2 for the DC sideA single device covers both lightning current discharge and the limitation of induced surges on the photovoltaic array.
Up to 1000V DCUcpv of 1000V DC with a withstand of 1200V DC, compatible with 1000V photovoltaic strings.
Iimp 12.5kA per pole, 25kA in totalLightning current on a 10/350 µs wave suited to installations equipped with lightning protection.
Y arrangement for one MPPTThe three-pole Y configuration simultaneously protects the PV+ to PE, PV− to PE and PV+ to PV− paths.
Local and remote signallingRed mechanical end-of-life module indicator and changeover contact rated 250V/0.5A AC or 30V/2A DC for remote signalling.
Wide temperature rangeOperation from -40 °C to +85 °C, with a self-extinguishing PEI enclosure rated UL94-V0.
