Type 1+2 combined lightning current and surge arrester

Maximum discharge capacity in an extremely compact design – and all for continuous voltages up to 440 V. The spark gaps in our type 1+2 combined lightning current and surge arresters feature extremely high performance thanks to the use of technology without any line follow current. This extends the life of the type 1+2 combined lightning current and surge arresters while also reducing the installation's load on your system.

The outstanding properties at a glance:

• Spark gap free of leakage current and line follow current
• Low voltage protection level
• Suitable for use in the unmetered area
• High lightning impulse current and high discharge capacity
• Ideal for use in lightning protection levels I/II

The robust type 1+2 combined lightning current and surge arresters feature a rated voltage of 800 V AC and a discharge capacity of 35 kA per channel, making them ideal for harsh industrial environments. The resistant housing design, shock values of 25 g and vibration resistance of 5 g make this type 1+2 combined lightning current and surge arrester ideal for wind turbine generators. The multi-level status indicator even allows you to detect the early stages of damage due to surge events.

• High rated voltage
• High shock and vibration resistance
• Multi-stage status indicator
• Use in harsh industrial environments

The varistor-based type 1+2 combined lightning current and surge arresters offer a discharge capacity of 12.5 kA per channel at a low residual voltage. They meet the requirements of lightning protection levels III and IV. You can perform recurring inspections quickly and and easily thanks to the pluggable design.

• Basic protection for all common applications
• Low voltage protection level
• Ideal for use in lightning protection levels III/IV
• Includes products for protecting photovoltaic systems
