3VA6325-5HN41-0AA0 SIEMENS

The 3VA6325-5HN41-0AA0 is a robust and reliable circuit breaker from Siemens, designed for comprehensive line protection in industrial and commercial applications. This 3VA6 UL frame 400 circuit breaker features a 4-pole configuration, ensuring complete isolation of the protected circuit. With a breaking capacity class M, it can handle fault currents up to 35kA at 480V, providing a high level of protection against overcurrents and short circuits. The integrated ETU350 electronic trip unit offers advanced protection functions, including adjustable overload protection (L), short-circuit protection with adjustable time delay (S), and instantaneous short-circuit protection (I). The rated current (In) is 250A, while the overload protection (Ir) can be adjusted from 100A to 250A to match specific load requirements. The short-circuit protection (Isd) is adjustable from 1.5 to 10 times Ir, and the instantaneous short-circuit protection (Ii) is set at 12 times In. This circuit breaker also includes adjustable N conductor protection (OFF, 50%, 100%), allowing for flexible configuration based on the specific system requirements. Note that this model does not include a connection for the neutral conductor. It adheres to UL standards, ensuring compliance with safety and performance requirements in North American markets. This circuit breaker is ideal for applications requiring reliable and adaptable circuit protection.
