The 920320 combination surge arrester module for 4 individual conductors from Dehn offers an effective solution for protecting electrical systems against overvoltages. This space-saving module is specifically designed for use with four individual conductors that share a common reference potential. A standout feature of the module is the integrated LifeCheck technology, which detects thermal and electrical overload conditions. When necessary, it indicates that the arrester needs to be replaced, significantly improving the maintenance and safety of the system. The non-contact display is facilitated through DEHNrecord LC / SCM / MCM, allowing for easy and secure monitoring. With a protection level of 18 volts and a nominal discharge current of 20 kA, this module is a reliable choice for surge protection.

• Integrated LifeCheck technology for monitoring overload conditions
• Non-contact display via DEHNrecord LC / SCM / MCM
• Protection level of 18 volts for effective surge protection
• Nominal discharge current of 20 kA for high load capacity.
