1. Application |
| |
DZ30 miniature circuit breaker is used in the single phase residual current of AC50/60Hz, rated voltage 220V or below for protecting electron circuit from overload and short circuitl This product has advantages of high breaking capacity, small volume, width is only 18mm. Zero and live wire are cut off at the same time, preventing the person and fire danger. It is the idealest distribution protective switch in the civil residence field at present. This product conforms to the requiremetn of IEC60898.
