3VA5320-7EF41-0AA0 SIEMENS

The 3VA5320-7EF41-0AA0 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, rated at 100kA at 480V, ensuring effective protection against high fault currents. It is specifically configured for line protection, utilizing a TM240 trip unit with an adjustable thermal-magnetic (ATAM) function. The rated current (In) is 200A, with an adjustable overload protection range (Ir) from 140A to 200A, allowing for precise customization to the specific load requirements. Short-circuit protection (Ii) is also adjustable, ranging from 5 to 10 times the rated current, providing fast response to short-circuit events. This model features a neutral pole that is unprotected, simplifying the design for applications where neutral protection is not required. The breaker is supplied without connection terminals, offering flexibility in choosing the appropriate connection method for the installation. Its UL certification ensures compliance with North American safety standards. This circuit breaker provides a comprehensive solution for safeguarding electrical systems against overloads and short circuits.
