Description
Legrand combination surge arrester type 1+2/Class I+II according to IEC/EN 61643-11, 3+1 circuit, for TT and TN-S systems, nominal voltage 230/400 V AC, lightning impulse current Iimp (10/350) 8 kA/pole. Maximum continuous voltage (Uc) 320 V AC. For protection against overvoltages of downstream consumers caused by indirect lightning strikes, switching operations and overhead line feed-in. With plug-in protection module and status display: Green (SPD ready for use) Orange (replace plug-in protection module).
