Basic parameters, working principle and purpose:
The SDB-A1~A50 pull-out free tripping three-phase circuit breaker products work on the principle of bimetallic electric thermal tripping and have a temperature compensation structure, which can be used in a wide temperature range. Circuit breakers are used for overload or short circuit protection in aircraft 115 V/two00C, 400 Hz three-phase AC distribution systems.
