3VA6340-5HN41-0AA0 SIEMENS

The 3VA6340-5HN41-0AA0 is a robust and reliable 3VA6 UL frame circuit breaker from Siemens, designed for comprehensive line protection in industrial and commercial applications. This 4-pole circuit breaker boasts a breaking capacity class M, capable of interrupting fault currents up to 35kA at 480V, ensuring the safety and integrity of electrical systems. Equipped with an ETU350 electronic trip unit, it offers advanced protection features, including LSI (Long-time, Short-time, Instantaneous) functions, providing precise and adjustable protection against overloads and short circuits. The rated current (In) is 400A, with an adjustable overload protection range (Ir) from 160A to 400A, allowing for customization to specific load requirements. Short-circuit protection (Isd) can be set from 1.5 to 10 times the Ir value, while instantaneous protection (Ii) is fixed at 10 times the In value, ensuring rapid response to high-level faults. The circuit breaker also incorporates adjustable N conductor protection, offering settings for OFF, 50%, and 100%, providing flexibility in neutral conductor management. This model comes without a connection, facilitating streamlined installation and integration into existing electrical panels. Siemens' 3VA6 series circuit breakers are known for their high performance, reliability, and ease of use, making them a preferred choice for demanding electrical protection applications. Its sophisticated protection settings and high breaking capacity make it suitable for a wide range of applications where reliable and precise circuit protection is essential.
