3VL5763-1TE46-0AA0 SIEMENS

The 3VL5763-1TE46-0AA0 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 interruption of fault currents. Equipped with an ETU20 trip unit, it offers comprehensive protection features tailored to diverse load requirements. The rated current (In) is 630A, with an adjustable overload protection range (IR) from 252A to 630A, allowing for precise customization. The short-circuit protection (ISD) can be set from 1.5 to 9 times the IR value, providing enhanced selectivity and coordination. Additionally, the instantaneous short-circuit protection (II) is fixed at 10 times the In value, ensuring rapid response to high-level faults. This circuit breaker is configured with N-pole unprotected, simplifying the installation and reducing the overall cost. It does not include an auxiliary release or auxiliary/alarm switch, making it suitable for applications where these features are not required.
