3VL4740-2EE46-0AA0 SIEMENS

The 3VL4740-2EE46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for high-performance circuit protection. This VL400H series breaker offers a high breaking capacity of Icu=70kA at 415V AC, ensuring reliable interruption of high fault currents. It is a non-automatic air circuit breaker, suitable for applications requiring manual reset after a trip. The trip unit is magnetic, providing instantaneous short-circuit protection. The rated current (In) is 400A, making it suitable for protecting circuits with a nominal current of 400 amperes. The instantaneous tripping current (II) is set at 4000A, providing short-circuit protection. This model is specifically designed for applications where immediate response to overcurrents is critical. It does not include an auxiliary release, simplifying the design and reducing potential points of failure. Furthermore, it is configured without auxiliary or alarm switches, focusing solely on core circuit protection functionality.
