3VL4725-1EJ46-0AA0 SIEMENS

The 3VL4725-1EJ46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It features a standard breaking capacity (Icu) of 55kA at 415V AC, ensuring effective interruption of fault currents. Equipped with an Electronic Trip Unit TM, LI, this circuit breaker offers precise and adjustable protection characteristics. The In=250A indicates the rated current, while the adjustable overload protection (IR=200...250A) allows customization to specific load requirements. The short-circuit protection (II=1250...2500A) provides rapid response to high-level fault currents. This model is specifically designed for systems where the neutral conductor does not require protection (N unprotected). It does not include an auxiliary release, simplifying the control circuit. Furthermore, the absence of auxiliary/alarm switches streamlines the breaker's operation and reduces complexity. This circuit breaker is ideal for applications demanding dependable overcurrent and short-circuit protection without the need for advanced monitoring or control features. Siemens' 3VL series is known for its quality and reliability in diverse industrial and commercial settings.
