Basic parameters, working principle and purpose:

DBF-1~35 pull-out free tripping single-phase circuit breaker products work on the principle of bimetallic electric thermal tripping and have temperature compensation structure, which can be used in a wide temperature range. The circuit breaker is used for dry overload short-circuit protection in aircraft AC/DC distribution systems.

Note: 1. DBF-0.5, DBF-4, DBF-30, DBF-35 can be customized according to customer needs

2. Can provide extended button series products Q/DBF-1L~35L

3. Can provide auxiliary contact series products (see DBF-1A~~35A for details)

4. Customers can choose circuit breaker accessories according to waterproof, dustproof, anti misoperation and other purposes
