The coordinated surge arrester DEHNbloc Maxi CI 440V AC Type 1 is a highly advanced protection device specifically designed for use in low-voltage consumer installations. It provides effective protection against overvoltages that can be caused by direct lightning strikes. With its spark gap base and integrated arrester pre-fuse, this surge arrester ensures high follow current extinguishing capability and limitation, supported by the innovative RADAX-Flow technology. The DEHNbloc Maxi CI is suitable for mounting on DIN rails and meets the requirements of test class Type 1 according to EN 61643-11. It is an essential component in the lightning protection zone concept, particularly at interfaces 0A and 1, offering reliable protection for electrical systems.

• High follow current extinguishing capability through RADAX-Flow technology
• Integrated arrester pre-fuse for additional protection
• Suitable for mounting on DIN rails
• Protection level of 2.5 volts (V)
• Lightning impulse current of 35 kiloamperes (kA).
