3VA5450-6EC61-0AA0 SIEMENS

The 3VA5450-6EC61-0AA0 is a robust and reliable molded case circuit breaker (MCCB) from Siemens' 3VA5 UL series, designed for comprehensive circuit protection in industrial and commercial applications. This two-pole breaker, part of Frame 600, offers a high breaking capacity, classified as H, capable of interrupting fault currents up to 65kA at 480V. It is specifically configured for line protection, utilizing a TM230 trip unit with a fixed thermal-magnetic (FTAM) setting. The rated current (In) is 500A, providing ample capacity for demanding loads. This particular model does not include overload protection, focusing solely on short-circuit protection. The fixed short-circuit protection (Ii) is adjustable within a range of 5 to 10 times the rated current (In), allowing for customization based on specific application requirements. Note that this circuit breaker is supplied without connection terminals, offering flexibility in choosing the appropriate connection method for the installation. This breaker ensures reliable and fast disconnection of the circuit in case of overcurrent or short circuit, preventing damage to equipment and ensuring safety. Its robust design and high breaking capacity make it suitable for use in various applications, including power distribution, motor protection, and generator protection.
