3VA6225-8HN31-0AA0

The Siemens SENTRON 3VA6225-8HN31-0AA0 functions as a molded case circuit breaker with a robust construction meant for residential or industrial setups. It operates on three poles and is rated for an insulation voltage up to 800 V, making it suitable for demanding applications. The device supports an operational voltage of up to 690 V AC, allowing it to manage various loads effectively.

This breaker is classified under Class L for breaking capacity, indicating high reliability when interrupting high fault currents. With a short-circuit breaking capacity rated at 150 kA at 480 V, the device ensures protection against severe overload conditions. The overcurrent release type used in this circuit breaker is ETU350, providing advanced trip settings.

Regarding trip settings, the long-time (L) trip range is adjustable between 100 A to 250 A, enabling it to hold specific loads effectively. For short-time (S) protection, the trip setting ranges from 375 A to 2500 A, readily responding to short circuit situations. Additionally, the instantaneous trip setting is fixed at 2500 A, allowing rapid disconnection in the event of severe overloads.

With a rated current of 250 A at an ambient temperature of 40°C, the Siemens 3VA6225-8HN31-0AA0 ensures stability and reliability for continuous usage. It is important to note that this mold breaker does not offer a neutral conductor upgrade, providing streamlined operation for standard circuit configurations.
