The Noark 110219 differential circuit breaker is designed to provide enhanced protection in both domestic and industrial settings. With an interrupting capacity (Icn) of 10kA and a nominal current (In) of 40A, this device is engineered to handle significant electrical loads. It features a residual current rating (IΔn) of 300mA and is classified as a Type B residual current circuit breaker.

Type B residual current circuit breakers are specifically tailored for use with equipment that generates complex waveforms, such as inverters, photovoltaic installations, and electric vehicle chargers. These breakers are sensitive to a variety of currents including sinusoidal residual currents, pulsed rectified currents, and smooth DC currents. They operate effectively at high frequencies up to 1 kHz.

The electronic technology foundation of these circuit breakers allows for a more accurate assessment of differential current, which in turn contributes to an extended lifespan of the device. Unlike standard solutions, these breakers do not suffer from internal circuit magnetization issues, which can lead to reduced maintenance and testing frequency. However, regular testing is still mandatory to comply with current regulations and standards. The product's EAN is 8592765102195.
