The 3VA6140-5HN41-0AA0 is a robust and reliable molded case circuit breaker (MCCB) from Siemens' 3VA6 series, designed for UL/CSA applications. This 4-pole circuit breaker, part of Frame 150, offers a breaking capacity class M, rated for 35kA at 480V, ensuring effective protection against overcurrents and short circuits in various electrical systems. It is specifically configured for line protection, incorporating an ETU350 electronic trip unit that provides precise and adjustable protection characteristics. The ETU350 offers LSI (Long-time, Short-time, Instantaneous) protection functions, allowing for customized settings to match specific load requirements. The overload protection (Ir) is adjustable from 16A to 40A, providing flexibility in adapting to different load profiles. Short-circuit protection (Isd) can be set from 1.5 to 10 times the Ir value, while instantaneous protection (Ii) is fixed at 12 times the rated current (In). Furthermore, this model includes adjustable N conductor protection, which can be set to OFF or 100%, offering enhanced safety and adaptability. This circuit breaker does not include a connection for neutral.
