3VL3725-1NA46-0AA0 SIEMENS

The 3VL3725-1NA46-0AA0 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 (ETU10), this circuit breaker offers precise and adjustable protection characteristics. The ETU10 includes a LIN (Line) module with a rated current (In) of 250A, allowing for flexible adaptation to various load requirements. The overload protection (IR) can be adjusted from 100A to 250A, providing a wide range of protection settings. Short-circuit protection (II) is configurable from 1.25 to 11 times the rated current (IN), enabling fast response to short-circuit events. This model provides N (Neutral) protection without an auxiliary release, simplifying installation and reducing component count. The 3VL3725-1NA46-0AA0 is communication-capable via ETU, allowing for remote monitoring and control. It does not include an auxiliary/alarm switch, focusing on core protection functionalities. This circuit breaker is ideal for applications requiring dependable and adaptable circuit protection.
