3VA5450-6EF41-0AA0 SIEMENS

The 3VA5450-6EF41-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. As part of the 3VA5 UL Frame 600 series, this circuit breaker offers a high breaking capacity, classified as H, capable of interrupting fault currents up to 65kA at 480V. It features a TM240 trip unit, providing adjustable thermal-magnetic protection. The rated current (In) is 500A, with an adjustable overload protection range (Ir) from 350A to 500A, allowing for precise customization to specific load requirements. The short circuit protection (Ii) is adjustable from 5 to 10 times the rated current, ensuring rapid response to short circuit events. This model is configured with a neutral conductor that is unprotected, and it does not include a connection for the neutral. This circuit breaker is designed for applications where a high level of protection and adjustability are required. The absence of overload protection on the neutral conductor makes it suitable for specific system configurations. It adheres to UL standards, ensuring compliance with safety and performance requirements. The ATAM functionality enhances its monitoring and control capabilities.
