The 3VA5340-5GC41-0AA0 is a robust and reliable UL-listed circuit breaker from Siemens, designed for comprehensive line protection in industrial and commercial applications. This 3VA5 series breaker features a frame size of 400, offering a breaking capacity class M, rated for 35kA at 480V. It is configured as a 4-pole breaker, ensuring complete isolation of the circuit during fault conditions. The breaker incorporates a TM230 trip unit, specifically calibrated for line protection duties. Its rated current (In) is 400A, providing ample capacity for demanding electrical loads. Notably, this model does not include overload protection (IR=400A fixed), focusing solely on short-circuit protection. The short-circuit protection (Ii) is adjustable from 5 to 10 times the rated current (In), allowing for fine-tuning of the protection characteristics. Furthermore, it offers 100% neutral protection, enhancing safety and preventing nuisance tripping due to neutral imbalances. The breaker is supplied without connection terminals, providing flexibility in installation and wiring configurations.
