The ARC-K-SYSTEM has been tested in line with EN 60439-1, Supplement 2: 2009 Criterion 1–7 and VdS Guideline 2349: 2000-02(01) Para. 4.2, in a high-performance test bay, installed in a MODUL-K-SYSTEM low-voltage switchgear unit made by KAUTZ Starkstrom-Anlagen.
The ARC-K-SYSTEM comprises a number of optical sensors arranged throughout the inside of the switchgear unit. It is able to detect an accidental arc in approx. 1,2 ms and triggers an extinguisher system which initiates a three-pole short circuit.
This results in the instant extinguishing of the accidental arc. The infeed switches are simultaneously deactivated. An uncontrolled release of energy is prevented and the accidental arc is safely contained.
