3VL5763-1NF46-0AA0 SIEMENS

The 3VL5763-1NF46-0AA0 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. The trip unit is an ETU20, providing comprehensive protection characteristics. The rated current (In) is 630A, with an adjustable overload protection range (IR) from 252A to 630A. Short-circuit protection is also included, with an adjustable instantaneous short-circuit setting (ISD) from 1.5 to 9 times the IR value, and a fixed short-circuit setting (II) at 10 times the In value. This model offers N-pole protection, enhancing safety and reliability. It does not include an auxiliary release but is communication-capable via ETU, allowing for remote monitoring and control. An auxiliary/alarm switch is not included in this configuration. This circuit breaker is suitable for a wide range of industrial and commercial applications where reliable and adjustable circuit protection is required.
