The AQ-1000 arc quenching device extinguishes arcing faults in systems with a maximum rated voltage of 690 V. The AQ-1000 arc quenching system is designed to limit the total arcing time to 4 ms and to minimize (or even eliminate) the damaging effects that an arc faultu2019s temperature and pressure cause. In most applications, this will result in an energy release of less than 1 cal/cmu00b2. AQ-1000 is fully resettable which allows for full system testing on-site.

AQ-1000 is used in conjunction with the AQ-100 arc protection system. When an AQ-100 series device detects a fault, it triggers the AQ-1000 arc quenching system and, simultaneously, trips the circuit breaker(s) feeding the fault. Then the AQ-1000 creates a low-impedance parallel path for the fault current to flow through, thus extinguishing the arc fault. The total arcing time is less than 4 milliseconds.
