The Noark 110228 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 3P+N configuration, ensuring that all three phases, as well as the neutral line, are monitored for differential currents.

Equipped with a residual current rating of 300mA, this Type B residual current device is sensitive to a variety of current types including sinusoidal residual currents, rectified pulsed currents, and smooth DC currents. It operates effectively with high-frequency disturbances up to 1 kHz, making it suitable for complex installations such as inverters, photovoltaic systems, and electric vehicle charging stations.

The use of advanced electronic technology in this circuit breaker allows for precise evaluation of differential currents, which contributes to an extended lifespan of the unit. Unlike standard solutions, it does not suffer from issues related to the magnetization of internal circuits. While the frequency of mandatory tests is reduced due to its robust design, adherence to applicable regulations and standards is essential. For the EX9LB63 series, routine testing every six months under normal conditions and monthly under severe contact conditions is recommended to ensure continued safety and performance. The product's identifier is 8592765102287.
