3VA5330-7EC41-0AA0 SIEMENS

The 3VA5330-7EC41-0AA0 is a robust 3VA5 UL frame circuit breaker from Siemens, designed for reliable circuit protection in industrial and commercial applications. This 4-pole 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 TM230 trip unit with fixed thermal-magnetic settings. The rated current (In) is 300A, with overload protection (Ir) fixed at 300A to prevent damage from sustained overcurrents. Short circuit protection (Ii) is adjustable between 5 to 10 times the rated current, providing flexibility in coordinating with downstream devices. The neutral pole is unprotected, simplifying the design for applications where neutral protection is not required. This circuit breaker does not include a connection and features FTAM front terminal connection. This model is engineered to meet UL standards, ensuring compliance with safety and performance requirements. Its compact design and comprehensive protection features make it suitable for a wide range of electrical distribution systems.
