TR300 arc protection used in MV & LV system But TR3000 arc quenching device extinguishes arcing faults in systems with rated voltage of below 690 V. The TR3000 arc quenching system is developed to limit the total arcing time to 5 ms and to minimize or even eliminate the arcing fault thermal and pressure damaging effects. In most applications this will result in a calorie/cm² energy release of less than 1. The TR3000 is fully reusable allowing for full system testing at site.
The TR3000 is utilized in conjunction with the TR3000 arc protection system. In case of an arc fault the TR3000 detects the fault, initiates the TR3000 arc quenching system and simultaneously trips the fault feeding circuit breaker(s). The TR3000 creates a three-Phase low-impedance parallel path for fault current to flow thus extinguishing the arc fault. The total arcing time is less than 5 ms.
