ACI-Technology

A further development of CI technology, ACI technology consists of a switch/spark gap combination connected in series with a heavyduty varistor. This ensures the simple design and safe operation of the surge protective device. Other features are safe dimensioning, TOV withstand, a connection cross-section of only 6 mm² Cu and zero leakage current. Surge arresters with ACI technology offer maximum safety and system availability.

ACI-Technology

A further development of CI technology, ACI technology consists of a switch/spark gap combination connected in series with a heavyduty varistor. This ensures the simple design and safe operation of the surge protective device. Other features are safe dimensioning, TOV withstand, a connection cross-section of only 6 mm² Cu and zero leakage current. Surge arresters with ACI technology offer maximum safety and system availability.

ACI-Technology

A further development of CI technology, ACI technology consists of a switch/spark gap combination connected in series with a heavyduty varistor. This ensures the simple design and safe operation of the surge protective device. Other features are safe dimensioning, TOV withstand, a connection cross-section of only 6 mm² Cu and zero leakage current. Surge arresters with ACI technology offer maximum safety and system availability.
