3VA9253-0JA11 SIEMENS

The 3VA9253-0JA11 is a molded case circuit breaker (MCCB) from Siemens' 3VA series. It is designed to provide reliable protection for electrical systems against overloads and short circuits. This particular model is a 3-pole breaker, meaning it protects three separate conductors. It has a rated current of 250A, indicating the maximum current it can continuously carry without tripping. The 3VA9253-0JA11 has a high breaking capacity, allowing it to safely interrupt high fault currents. It is suitable for use in a variety of applications, including industrial, commercial, and residential settings. The breaker features a thermal-magnetic trip unit, which provides both overload and short-circuit protection. The thermal element responds to sustained overcurrents, while the magnetic element reacts instantly to short circuits. This combination ensures comprehensive protection for electrical equipment and personnel. The 3VA series is known for its compact design and easy installation.
