3VA5225-0MU31-0AA0 SIEMENS

The 3VA5225-0MU31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for starter protection applications within UL-rated systems. This model falls under Frame 250, indicating its capacity and physical dimensions. It features a TM120M trip unit, configured for AM (Starter Protection) functionality. The circuit breaker has a rated current (In) of 250A, suitable for handling substantial electrical loads. Notably, this particular model does not include overload protection, focusing primarily 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 breaker is designed without connection terminals, allowing for flexible integration into various electrical systems using appropriate connectors. It ensures reliable interruption of current in the event of a short circuit, safeguarding connected equipment and preventing electrical hazards. The 3VA5225-0MU31-0AA0 is ideal for applications where dedicated starter protection is required, and overload protection is managed separately. Its robust design and precise short-circuit response make it a dependable component in critical electrical circuits.
