Iimp 12.5kA Type 1+2 Surge Protective Device Class I+II SPD Class B+C Surge Arresters
Iimp 12.5kA Type 1+2 Surge Protective Device Class I+II SPD Product Description:
• BR-12.5M is surge arrester type 1+2 and class I+II according to EN 61643-11 and IEC 61643-1.
• The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current.
• Complete device consists of a base part and pluggable module.
• High arresting capacity up to 12.5 kA (10/350μs)
• The visual indication of green and red indicator flags shows the proper functioning of every protective circuit and varistor.
