3VL6780-1NA46-0AA0 SIEMENS

The 3VL6780-1NA46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It features a standard breaking capacity of Icu=55kA at 415V AC, ensuring effective interruption of fault currents. Equipped with an ETU10 trip unit, this circuit breaker offers precise and adjustable protection characteristics. The rated current (In) is 800A, while the overload protection (Ir) can be adjusted from 320A to 800A, providing flexibility to match specific load requirements. The short-circuit protection (Ii) ranges from 1.25 to 8 times the rated current (IN), offering fast response to short-circuit events. This model provides N-pole protection without an auxiliary release, simplifying installation and reducing component count. The ETU is communication-capable, enabling remote monitoring and control for enhanced system management. However, it does not include an auxiliary/alarm switch. This circuit breaker is ideal for applications requiring dependable protection and adjustable settings.
