3VA5105-1MU31-0AA0 SIEMENS

The 3VA5105-1MU31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for starter protection within UL frame 125 applications. This circuit breaker utilizes a TM120M trip unit, specifically configured for AM (Starter Protection) applications. It has a rated current (In) of 5A, making it suitable for protecting circuits with relatively low current demands. Notably, this model does not feature overload protection, focusing solely on short-circuit protection. The short-circuit protection (Ii) is set at 3 to 7 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 3VA5105-1MU31-0AA0 is designed without connection terminals, offering flexibility in installation and connection methods. This circuit breaker is ideal for applications where starter protection and short-circuit protection are paramount. Its compact design and reliable performance make it a valuable component in various electrical systems. Siemens' commitment to quality ensures long-lasting and dependable operation.
