3VA5325-0MU31-0AA0 SIEMENS

The 3VA5325-0MU31-0AA0 from Siemens is a robust 3-pole circuit breaker designed for motor starter protection within UL Frame 400 applications. This circuit breaker features a TM120M trip unit, specifically configured for AM (Motor Starter Protection) functionality. It has a rated current (In) of 250A, making it suitable for protecting circuits with substantial current demands. Notably, this model does not include overload protection, focusing solely on short circuit protection. The short circuit protection (Ii) is set at 3 to 6 times the rated current (In), providing rapid response to fault conditions. This ensures quick disconnection of the circuit in the event of a short circuit, minimizing potential damage. The 3VA5325-0MU31-0AA0 is designed without connection terminals, offering flexibility in installation and connection methods. It is ideal for applications where dedicated motor starter protection is required, and external overload protection is provided. Siemens' 3VA5 series circuit breakers are known for their reliability and performance in demanding industrial environments. This particular model offers a specialized solution for motor protection, prioritizing short circuit interruption.
