Type 1+2 varistor-spark-gap surge protecor, used to protect photovoltaic installations in networks with a maximum voltage of 1200V DC. It complies with all current standards. Thanks to the replaceable inserts, it is possible to quickly replace the faulty module in case of damage. The limiter is made in a Y-connection system, in the patented VG technology, which prevents passive aging of the apparatus, because there are no operating currents and leakage current.
