High-voltage surge arrester / type 1 / polymer - 9 - 36 kV | INZP series
The Polymeric INZP surge arrester tested and certified with the latest industry standard ANSI/IEEE C62.11 - 1993 for metal oxide arresters in addition to the IEC 99 - 4 for class line. These arresters are specifically designed to provide the complete set of benefits equipped by the metal oxide distribution arrester in light-weight, low profile polymeric housing suitable for both indoor and outdoor overhead applications.
The issues related with chipped or cracked porcelain, that arise due to rough handling or shipping, are completely eliminated by the polymeric housings. The porcelain housed units result in failure mode that are much severe than that arising with these INZP arresters.
In case of failure conditions with polymer housings, these INZP arresters split open in order to relieve the internal pressure. Unlike these, the case with porcelain housing is disastrous. When a violent failure condition arises with porcelain housings, thermal fracture of the porcelain housing occurs due to the internal arc from excessive fault current, which in turn causes the hot gases created by the arc to explode the porcelain fragments in all directions.

Low-voltage surge arrester / type 1 / DIN rail - 12.5 kA | DGM
The DGM is a compact (two-pole) Type 1 AC Surge Protection Device (SPD) dedicated to be connected
at the entrance of the electrical installation. Particularly useful in a high lightning density area, this SPD is designed to provide an efficient protection for sensitive equipment against over voltage due to lightning effects or industrial interferences.
The DGM is a single-phase SPD and can be also used for 3-phase N AC networks protection (made of 2 DGM).
Protection is based on high energy varistors diagram which is able to channel currents of up to 100 kA to
earth without incurring damage. According to the latest issue of IEC 62 305 and IEC 60 364 standards,
it is compulsory to install those surge arresters on the incoming power supply if the building is fitted
with external lightning protection system. Multiple stage protection can be achieved using DGM
surge arresters at the network entrance combined with DGT or DGX surge
arresters positioned as close as possible to sensitive equipments.
