Disclosed is a bidirectional current limiting static circuit breaker including four power thyristors arranged to form two conducting paths. Each path includes two of the thyristors and a common current limiting inductor. Commutation means are provided to render any fault current carrying power thyristors non-conductive upon command. The current limiting inductor acts to insure that commutation proceeds to a successful conclusion once begun. The breaker also includes means for suppressing commutation induced transients and for protecting nonconducting power thyristors from externally originated voltage surges.
