385v/420v electrical surge din rail 4 pole surge arrester type 2 40ka ly1 c40 4p

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

SPD Surge protection against low voltage and photovoltaic systems. A move to limit LPZ 1 zones LPZ LPZ 2 or 3. Complies with EN 61643-11 on arresters connected to low voltage distribution systems. Technology "Upside Down Mounting". Contact for remote monitoring of the state of the varistor: presence, operating, replace. Mounting on 35 mm rail (EN 60715).

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 high energy varistors (or combination high energy varistor spark gap).

This technology provides an excellent level of protection.
