3VA5220-7EF31-0AA0 SIEMENS

The 3VA5220-7EF31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. It falls under the 3VA5 UL frame 250 series, ensuring high performance and safety. This circuit breaker boasts a breaking capacity class C, capable of interrupting fault currents up to 100kA at 480V, providing excellent protection against overcurrents and short circuits. Equipped with a TM240 trip unit, it offers advanced protection features with adjustable parameters. The ATAM (Adjustable Thermal and Magnetic) functionality allows for precise customization of protection settings. The rated current (In) is 200A, while the overload protection (Ir) can be adjusted from 160A to 200A, providing flexibility to match specific load requirements. For short-circuit protection, the instantaneous tripping current (Ii) is set at 5 to 10 times the rated current (In), ensuring rapid response to fault conditions. This model is designed without connection terminals, allowing for versatile installation options based on specific application needs. Siemens 3VA5 circuit breakers are known for their reliability, durability, and advanced protection features, making them a preferred choice for demanding electrical systems.
