ProTec AQS

The ProTec AQS overvoltage surge protective device has been developed to protect against indirect lightning discharges on overhead power lines. The Class II SPD consists of a high-performance varistor with a disconnection device that protects against short circuit conditions.
The ProTec AQS complies with IEC/EN 61643-12 standards and features a silicon jacket for greater hermetic sealing properties.
