DZ30L-32( DPNvigi) protection circuit breaker applies to the exchange of 50HZor 60Hz, rated voltage 230v single phase residential line, as leakage protection and use of civilian overload electrical circuits and short-circuit protection, the product is small in size, high breaking capacity: Zero, the battle line at the same time cut, and then in the firing line against the circumstances, despite the leakage protection, the produces meet IEC1009GB16917.1-1997 standards. Electrical leakage over voltage protection circuit breaker with the filtering device, to prevent the instantaneous voltage (lighting and other equipment lines interference ). And instantaneous currents (such as the large capacitive load line )caused by disoperation release.
