The Eaton Industries MCCB Circuit-breaker NZM3 is a 3-pole power switch that has a switching capacity of 400/415V at 50Hz. Its interrupting capacity (Icu) is 50 kA and it has a rated current of 500A, which equals its rated uninterrupted current (In = Iu). It is designed for fixed installation and uses a screw connection for easy installation. This component has been built as per IEC standards and offers protective function, which includes system and cable protection.
