AC Surge Protection

Features and benefits

• Impulse test classification: Test class I and II according to IEC 61643-11 Ed. 1 (2011-03) and Type 1 and 2 according to EN 61643-11 (2012-10);
• This is a voltage limiting SPD for the protection of low voltage installations and equipment against direct and indirect lightning effects;
• Backup protection is not required with an upstream CB ≤ 160 A or up to an Isccr ≤ 5 kA rms;
• The impulse current is divided into two independent branch circuits, each branch providing its own disconnector and Status Indicator;
• Three colour Status Indicator with progressive indication of remaining performance.
