3VL5763-1NB46-0AA0 SIEMENS

The 3VL5763-1NB46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. This VL630N model boasts a standard breaking capacity of Icu=55kA at 415V AC, ensuring effective protection against overcurrents and short circuits. Equipped with an ETU10 trip unit, it offers precise and adjustable protection characteristics. The rated current (In) is 630A, while the overload protection (IR) can be adjusted from 252A to 630A, providing flexibility to match specific load requirements. The short-circuit protection (II) is adjustable from 1.25 to 10 times the rated current (IN), allowing for tailored protection against high-level fault currents. This circuit breaker is designed without an auxiliary release, simplifying installation and reducing potential points of failure. Furthermore, the ETU is communication-capable, enabling integration into modern energy management systems for remote monitoring and control. It does not include an auxiliary/alarm switch. This Siemens circuit breaker combines high performance with advanced features, making it a suitable choice for demanding electrical protection applications.
