AQ-2000 Arc quenching device | 42technology

AQ 2000 arc quenching system extinguishes arcing faults within 6ms of arc initiation. The AQ 100 by Arcteq is a reliable and fast acting dedicated arc protection system. providing excellent protection against arcing thermal effects by tripping the sourcing circuit breaker (s) almost instantly. When protecting against arcing fault pressure effects circuit breakers are sometimes not fast enough as the pressure wave builds up within the first 10ms of the fault.Get price

What is quenching an arc? - Standex Electronics

When the reed contacts open they break a circuit. If there is a voltage and current present when the contacts open they will stop the current flow. Once the contacts open the voltage that was driving the current will reappear across the contacts. This is normally not an issue unless the voltage is generally higher than 250 volts. At this level and higher when the contacts attempt to open theyGet price
