APPLICATION
       This breaker is applicable to a line of AC 50Hz/60Hz, rated voltage 240V and rated current to 32A, used to protect the line from overload and short circuit. It can also be used for infrequent line conversion under normal condition. It is a phase wire + neutral wire type breaker newly developed by our company, which can be switch off phase wire and neutral wire simultaneously and features small volume and high safe performance. For a single-pole breaker, the phase wire and neutral wire are easy to be mis-connected or the potential of neutral wire to ground may be higher, thus it may result in dangerous fire and injuring people. This household breaker eliminates such shortages. It is applicable to office buildings, dwelling houses, and so on.
