SIQuench 3AM4143 is an arc quenching device which extinguishes arcing faults within 5 milliseconds of arc initiation. The device is installed as a part of an AQ 100 arc protection system. When an AQ 100 series device detects an arc fault, it simultaneously triggers the SIQuench arc quenching system and trips the circuit breaker(s) that feed the fault. Then, the SIQuench unit creates a low-impedance parallel path for the fault current to flow through. The total arcing time is less than 5 milliseconds, which mitigates the risk of personal injuries and of damages to the equipment.
- Auxiliary supply ranges from 110 to 250 V AC/DC.
- Includes the controller (trigger device) and connection cables.
- Additional connection fibers (3 m, 5 m & 10 m) available.
- Applicable to both new and retrofit installations.
