3VL4731-1NA46-0AA0 SIEMENS

The 3VL4731-1NA46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It features a standard breaking capacity (Icu) of 55kA at 415V AC, ensuring effective protection against overcurrents and short circuits. Equipped with an Electronic Trip Unit ETU10, this circuit breaker offers precise and adjustable protection characteristics. The ETU10 allows for setting the rated current (Ir) within a range of 128 to 315A, providing flexibility to match specific load requirements. Overload protection is configurable, with an adjustable range of 1.25 to 11 times the rated current (In), safeguarding against prolonged overloads. Short-circuit protection is also integrated, enhancing the overall safety of the electrical system. This model does not include an auxiliary release and offers N protection. Furthermore, the ETU is communication-capable, enabling integration into monitoring and control systems. Note that this model does not include an auxiliary/alarm switch.
