3VL2708-3EJ43-0AA0 SIEMENS

The 3VL2708-3EJ43-0AA0 is a robust 4-pole circuit breaker from Siemens' VL series, designed for line protection in electrical systems. This model boasts a very high breaking capacity (Icu) of 100kA at 415V AC, ensuring reliable performance under demanding conditions. Equipped with an Electronic Trip Unit TM, it offers precise and adjustable protection characteristics. The rated current (In) is 80A, with an adjustable overload protection range (IR) from 63A to 80A, allowing customization to specific load requirements. The short-circuit protection (II) is set between 400A and 800A, providing rapid response to fault currents. This circuit breaker is specifically configured with N unprotected, meaning the neutral conductor is not protected by the breaker's tripping mechanism. It does not include an auxiliary release, simplifying the design and reducing potential points of failure. Furthermore, it is supplied without an auxiliary or alarm switch, focusing on core circuit protection functionality. The 3VL2708-3EJ43-0AA0 is ideal for applications requiring high interrupting capacity and adjustable protection settings.
