Arresters type 2 or SPD (Surge Protection Devices) are installed in electrical distribution networks to protect people, installations and equipment surges caused by lightning or power surges forwarders. Can be used in systems between LN and L-PEN. Visual indication of the status of the varistor: good condition or replaced.

Arresters are designed to protect electrical installations of atmospheric overvoltages (lightning) or industrial (overvoltage, switching inductive loads, etc..).

In areas where storms are frequent, it is strongly recommended to install additional protection systems. The additional cost of the equipment and its installation is always outweighed by greater immunity limited on-site interventions and avoid premature wear electronic circuits. Do not wait for disaster that could cost you dearly! The maximum load current (I max / shock) were tested with a pulse of 1.250 microseconds 8/20?S voltage and current.

Type 2 surge arresters are designed for installations where direct lightning strike risk is reduced (without LPS or medium risk). They are also used in addition to the SPD type 1 in order to limit the operating voltage arresters (level of protection).

These devices are connected to either end of the installation (in the case of use in primary SPD) or in distribution cabinets (when used in addition to the SPD type 1) They incorporate technology-based varistors high energy (or combination high energy varistor spark gap). This technology provides an excellent level of protection.
