Short circuit test, 3kA solid-state DC breaker switch

Short circuit test, solid-state 3kA DC breaker switch

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.

Interested in the impressive fault clearance of our solid-state DC breaker switches?

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.
