DZ30-32(phase line+neutral line leakage) series miniature circuit breaker is suitable to the single phase residual circuit of 50/60Hz, rated voltage 230V, as the current leakage protection and protect the civil electrical circuit from over load and short circuit and it has the features of volume small, breaking capacity high. Null/live wire is cut at the same time, and even the wire is reverse connection, it still have current leakage Protection.The product conforms to standards IEC1009.1, GB16917.1etc.

BREAKING CHARACTERSTIC CURVE
1. Press the test button once a month, check leakage protective device.
2. When the leakage protective device, the device on the obverse of the red machine instructions.
3. When reclosing circuit breaker, the protection device reset automatically.
