3VA5340-7EF41-0AA0 SIEMENS

The 3VA5340-7EF41-0AA0 is a robust 3VA5 UL frame circuit breaker from Siemens, designed for reliable circuit protection in industrial and commercial applications. This 4-pole circuit breaker offers a breaking capacity class C, capable of interrupting fault currents up to 100kA at 480V. It is configured for line protection, utilizing a TM240 trip unit with an adjustable thermal-magnetic (ATAM) function. The rated current (In) is 400A, with an adjustable overload protection range (Ir) from 280A to 400A, allowing for precise customization to specific load requirements. Short-circuit protection (Ii) is set at 5 to 10 times the rated current, ensuring rapid response to high-fault conditions. This model features an unprotected neutral pole, suitable for systems where neutral protection is not required. The breaker is supplied without connection terminals, providing flexibility in selecting appropriate connection methods. It is engineered to meet UL standards, ensuring compliance with safety and performance requirements. This circuit breaker provides a comprehensive solution for safeguarding electrical systems against overloads and short circuits.
