ENT-50R Safety Circuit Breaker

Function

ENT-50R series of residual current circuit breaker ,apply to the circuit of AC50Hz,rated voltage 230V/115V,ratedcurrent to 32A single phase circuit. Its main function is to provide protection for person to avoid the potentially lethal byan electric shock. At the same time, it can also be used to prevent electrical fires caused by equipment connected to the  damage, ground fault current. This series of derived products also have the function of overload protection, which caneffectively prevent burn out electrical equipment.

This series of residual current circuit breaker with small volume, high breaking, reliable operation and environmental protection, et, which can be widely used in electric water heater, solar water heater, vending machines, water dispensers, refrigerators, washing machines and other electrical equipment to provide the protection avoid electric shock、electric leakage and overload, which are ideal products to users. This series of products are in conformity with IEC61008 and IEC61009 standards.
