RCCB, Icn=10kA, 3P+N, In=40A, IΔn=300mA, type B

Noark residual current circuit breakers are suitable for both domestic and industrial applications using inverters, photovoltaic installations, electric vehicle chargers, etc. Type B residual current circuit breakers are sensitive to sinusoidal residual currents, as well as pulsating and smooth direct currents. These circuit breakers feature a high frequency of up to 1 kHz. They are based on electronic technology, which brings benefits in the form of a more precise evaluation of the residual current, consequently extending the lifespan of the device. These breakers do not encounter difficulties related to the magnetization of internal systems, as is the case with standard solutions. This allows for reducing the frequency of recommended tests; however, they must still be performed regularly, in accordance with applicable regulations and standards.
