Basic parameters, working principle and purpose:

The DBH-25-35 pull-out free tripping single-phase circuit breaker works on the principle of combining bimetallic electric heating and electromagnetic tripping, and has a temperature compensation structure that can be used in a wide humidity range. The circuit breaker is used for overload or short circuit protection in aircraft AC/DC distribution systems.
