3VA5191-1MU31-0AA0 SIEMENS

The 3VA5191-1MU31-0AA0 is a robust and reliable circuit breaker from Siemens, designed for optimal performance and protection in various electrical applications. This particular model is part of the 3VA5 UL frame series, indicating its compliance with Underwriters Laboratories (UL) standards for safety and performance. It features a 3-pole configuration, making it suitable for three-phase systems commonly found in industrial and commercial settings. Specifically configured for starter protection, this circuit breaker utilizes a TM120M trip unit, which is optimized for motor protection applications. The TM120M trip unit includes an AM (Ampere Meter) function, providing real-time current monitoring for enhanced control and diagnostics. With a rated current (In) of 10A, it is designed to handle moderate current loads efficiently. Notably, this model does not include overload protection, focusing primarily on short-circuit protection. The short-circuit protection (Ii) is set at 3 to 7 times the rated current (3...7 x In), ensuring rapid response to fault conditions. This circuit breaker is supplied without connection terminals, offering flexibility in installation and integration with different wiring systems. This allows users to select the most appropriate connection method for their specific application, enhancing adaptability and ease of use.
