Siemens 5SD7483-6 DC surge arrester Type 1+2, 1000V, for photovoltaics

The 5SD7483-6 is the combined Type 1+2 arrester of the SENTRON range for the DC side of a photovoltaic system: it protects inverter and wiring from both direct lightning discharge and induced surges.

It works up to 1000V DC with an impulse current of Iimp 5kA (10/350 µs), a nominal discharge current of In 15kA and a maximum of 40kA (8/20 µs), holding the protection level at 3.5kV. It mounts on a 35 mm DIN rail, takes three modules, has an optical status indicator and replaceable cartridges. Compliant with EN 50539-11 and EN 61643-11.

Key strengths

Type 1 and Type 2 in oneA single device for direct lightning and induced surges.
Up to 1000V DCCovers residential and commercial PV strings.
Up 3.5kVKeeps the residual surge within the inverter withstand level.
Replaceable cartridgesAfter an event you change the insert, not the whole device.
Optical indicatorYou can see at a glance when a cartridge is spent.
DIN railFits the string board like any modular device.

The arrester must be installed as close as possible to the inverter and earthed by the shortest possible path: that is what determines the real protection level.
