Dowei Electric MV Fault Current Limiter FCL

Product catalog summary

General Description:

The MV Fault Current Limiter adheres to international standards such as IEC 62271-1, IEC 60282-1, IEEE Std C37.302, and NEMA, ensuring high quality and reliability.
Certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA, it meets rigorous quality and safety standards.
Designed to withstand seismic activities as per ETGI-1.020, IEEE Std 693, and NCh2369.
Structural integrity is ensured through compliance with ASTM A325, ANSI/AISC 360, and AWS D1.1.
Capable of high altitude operation up to 5000 meters, following IEC 62271 and IEEE C37 guidelines.
Reduces harmonics, voltage sags, and flicker by lowering total source impedance.
Offers high and fast fault-current breaking capability at high operating currents, suitable for medium voltage ratings up to 40.5kV, 6,300A, and 200kA rms breaking capability.
Customizable settings for instantaneous current and rate of current rise.

Typical Specification:

Rated voltage options: 7.2, 12, 17.5, 24, 36, and 40.5 kV.
Rated current range: 1250 to 6300 A, depending on the voltage.
Operates at frequencies of 50/60 Hz.
Short-circuit breaking current capability up to 200 kA rms.
Short-time withstand voltage ranges from 20 to 95 kV, depending on the rated voltage.
Impulse withstand voltage (BIL) ranges from 60 to 185 kV.
Tripping time is less than 1 ms, with a total operating time of less than 10 ms.
Peak current limiting ratio ranges from 15% to 50%.
Rated auxiliary voltage options: DC 110, 220; AC 110, 220.
Can be installed indoors or outdoors.
