3VA5195-4EF41-0AA0 SIEMENS

The 3VA5195-4EF41-0AA0 is a robust and reliable UL-listed circuit breaker from Siemens, designed for optimal circuit protection in industrial and commercial applications. This 3VA5 series breaker features a frame size of 125 and a breaking capacity class S, capable of interrupting fault currents up to 25kA at 480V. It is configured as a 4-pole breaker, making it suitable for three-phase systems with a neutral conductor. The breaker incorporates a TM240 trip unit, specifically designed for line protection, ensuring reliable performance and preventing nuisance tripping. The adjustable thermal overload protection (Ir) allows for fine-tuning the tripping current between 12A and 15A, providing precise protection against sustained overloads. Instantaneous short-circuit protection (Ii) is set at 1020 times the rated current (In), offering rapid response to high-level fault currents. This model is designed with an unprotected neutral conductor and does not include a neutral conductor connection. The ATAM (Adjustable Thermal, Adjustable Magnetic) functionality provides flexibility in setting both overload and short-circuit protection parameters. This circuit breaker is ideal for applications requiring dependable protection against overloads and short circuits in electrical distribution systems.
