3VA5460-0MU31-0AA0 SIEMENS

The 3VA5460-0MU31-0AA0 from Siemens is a robust 3-pole circuit breaker designed for motor starter protection within UL Frame 600 applications. This circuit breaker offers a reliable solution for safeguarding motor circuits against short circuits. Featuring a TM120M trip unit, it provides adjustable magnetic short-circuit protection (AM) with a rated current (In) of 600A. The short circuit protection (Ii) is configurable from 3 to 6 times the rated current, allowing for precise coordination with motor starting characteristics. Note that this model does not include overload protection, focusing solely on short-circuit interruption. This ensures rapid response to fault currents, minimizing potential damage to connected equipment. The absence of connection terminals simplifies installation and allows for flexible integration with various busbar systems or terminal blocks. It is ideal for applications where a separate overload relay provides motor overload protection. The 3VA5460-0MU31-0AA0 circuit breaker delivers dependable performance and enhances the safety and reliability of motor control systems. This device adheres to stringent quality standards, ensuring long-term operational stability.
