3VL3725-1TE46-0AA0 SIEMENS

The 3VL3725-1TE46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It features a standard breaking capacity of Icu=55kA at 415V AC, ensuring effective interruption of fault currents. Equipped with an Electronic Trip Unit ETU20, this circuit breaker offers advanced protection and control capabilities. The rated current (In) is 250A, with an adjustable overload protection range (IR) from 100A to 250A, allowing for precise customization to specific load requirements. The short-circuit protection (ISD) can be set from 1.5 to 10 times the IR value, providing enhanced protection against short-circuit events. Additionally, the instantaneous short-circuit protection (II) is set at 11 times the In value for rapid response to high-level faults. This model is designed with N unprotected and does not include an auxiliary release or auxiliary/alarm switch. It is suitable for applications requiring dependable circuit protection without the need for additional signaling or remote tripping features. The 3VL3725-1TE46-0AA0 circuit breaker provides a comprehensive solution for safeguarding electrical circuits against overloads and short circuits.
