DZ47LE-63 household residual current circuit breaker

DZ47LE-63seriesLeakage circuit breakerThe residual current circuit breaker (hereinafter referred to as RCCB) is suitable for use in circuits with AC 50Hz, rated voltage up to 400V, and rated current up to 50A. It is used for leakage and overload protection, to prevent fire or personal injury accidents caused by circuit leakage or electric shock, and can also provide overvoltage protection against excessive voltage rise caused by power grid failures.
The DZ47LE-63 series residual current circuit breaker is a current operated electronic residual current circuit breaker, consisting ofDZ47 circuit breakerCombined with residual current release device. When there is leakage or personal electric shock in the protected circuit, as long as the leakage current I △ reaches the operating current value, the circuit breaker will immediately operate, cut off the power supply, and thus play a role in leakage and electric shock protection. At the same time, the leakage circuit breaker can also protect against overload and short circuit in the circuit.
Circuit breakerMeets the requirements of standards such as IEC61009-1:1996 and GB16917.1 "Residual Current Operated Circuit Breakers with Overcurrent Protection for Household and Similar Purposes (RCBO) Part 1: General Rules".
