Basic parameters, working principle and purpose:

DBF-1A~20A 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. Circuit breakers not only provide overload and short-circuit protection for power lines or electrical equipment, but also have the function of monitoring the on/off status of products.
