AQ 100

The efficient arc protection system

It is built to meet the growing demands in both LV and MV switchgear and controlgear applications ranging from basic stand-alone to more complex system solutions.

Application range of the AQ 100

The AQ 100 series is designed and tested according to the latest protection relay standards and is hence suitable for installations in any environment, such as utility, power plant, wind-power, off shore, marine, oil and gas, mining, steel or any other heavy industry application and as well commercial and institutional electrical systems. The AQ 100 modular design makes it an excellent candidate for both new and retrofit installations.
