Interested in the impressive fault clearance of our solid-state DC breaker switches?
Our range of solid-state DC breaker switches enable safe and SMART DC power systems. Thanks to the ultra-fast switch-off times this IGBT-based technology protects (onboard) DC power grids against arcing, power overload and short-circuit situations.
Please check out our short circuit test of the 3kA DC breaker switch under full load conditions at the high-voltage test lab of Astrol Electronic AG in Switzerland.
Details of the test:
- 5 kA current source
- 3 kA DC breaker switch
- 850 V
- 1.2 μH inductance
- dI/dt: 690 A μs
- l off: 9,92 kA
- Clearing time 12 μs!
