3VA5215-1MU31-0AA0 SIEMENS

The 3VA5215-1MU31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for starter protection within UL frame 250 applications. This circuit breaker is equipped with a TM120M trip unit, configured for AM (Starter Protection) functionality. It has a rated current (In) of 150A, making it suitable for protecting circuits with substantial current loads. Notably, this 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 ensures quick interruption of the circuit in the event of a short circuit, minimizing potential damage to connected equipment. The absence of connection terminals allows for flexible integration with various connection systems based on specific application requirements. This circuit breaker is ideal for applications where dedicated starter protection is required, and external overload protection is provided. Its reliable performance and compliance with UL standards make it a dependable choice for industrial and commercial settings. The 3VA5215-1MU31-0AA0 offers a compact and efficient solution for safeguarding motor starters against short-circuit faults.
