3VA5215-0MU31-0AA0 SIEMENS

The 3VA5215-0MU31-0AA0 from Siemens is a robust 3-pole circuit breaker designed for starter protection within UL frame 250 applications. This circuit breaker features 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 moderate current demands. 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 to prevent damage to connected equipment. The 3VA5215-0MU31-0AA0 is designed without connection terminals, offering flexibility in choosing appropriate connection methods based on specific installation requirements. This circuit breaker is well-suited for applications where starter protection and short-circuit interruption are critical, and where overload protection is provided separately or not required. Its compact design and reliable performance make it a valuable component in various industrial and commercial electrical systems. Siemens is a trusted brand, ensuring high quality and adherence to safety standards. The absence of overload protection simplifies the breaker's function, focusing on rapid response to short circuits.
