Surge Arrester – Type 2

AQ30-280

AQ30-400

This surge arrester contains a decou­pling device, which protects a module against short circuit condi­tion, installation for outdoor mounting. Protection is provided on power lines and is capable of discharging enor­mous pulse currents. In case of permanent arrester damage thermal protection will be activated. The protective com­ponent interrupts the circuit and after activation of disconnecting device earth conductor is visibly separated.
