3VA5325-1MH31-0AA0 SIEMENS

The 3VA5325-1MH31-0AA0 is a robust 3-pole molded case circuit breaker from Siemens, designed for motor starter protection applications under UL standards. This particular model falls within the Frame 400 category, indicating its capacity to handle substantial current loads. It features a TM120M trip unit, optimized for 'AM' type selectivity, ensuring reliable coordination in electrical systems. The circuit breaker has a rated current (In) of 250A, suitable for protecting circuits with corresponding current demands. Notably, this model does not include overload protection, focusing solely on short-circuit protection. The short-circuit protection (Ii) is set at 6 to 12 times the rated current (In), providing rapid response to fault currents. This ensures quick interruption of the circuit to prevent damage to equipment and minimize downtime. The 3VA5325-1MH31-0AA0 is designed without connection terminals, allowing for flexible installation options based on specific application requirements. This circuit breaker is ideal for applications where selective short-circuit protection is paramount, and overload protection is handled separately. Its robust design and precise engineering make it a reliable component in demanding industrial environments.
