3VA5145-6ED31-0AA0 SIEMENS

The 3VA5145-6ED31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. It falls under the 3VA5 UL frame 125 series, ensuring compatibility and ease of integration within existing systems. This circuit breaker boasts a high breaking capacity class H, capable of interrupting fault currents up to 65kA at 480V, providing enhanced safety and protection against electrical hazards. Equipped with a TM210 trip unit, it offers fixed thermal-magnetic protection, simplifying setup and ensuring consistent performance. The overload protection is set at Ir=45A, safeguarding circuits from sustained overcurrents. The fixed short-circuit protection is configured at Ii=10 x In (10 times the rated current), providing rapid response to short-circuit events. With a rated current of In=45A, this circuit breaker is suitable for a variety of applications requiring moderate current levels. This model does not include a connection, allowing for flexible wiring configurations based on specific installation requirements. The FTFM functionality further enhances its performance and reliability in demanding environments.
