3VL5763-2UN46-0AA0 SIEMENS

The 3VL5763-2UN46-0AA0 is a high-performance circuit breaker from Siemens, designed for line protection in industrial and commercial applications. This 4-pole circuit breaker is part of the VL series, known for its reliability and robust construction. It features a high breaking capacity of Icu=70kA at 415V AC, ensuring effective protection against short circuits and overloads. The trip unit is an LCD ETU42, providing advanced electronic trip functionality with adjustable parameters. The rated current (In) is 630A, with an adjustable overload protection range (IR) from 252A to 630A. The short-circuit protection (ISD) can be set from 1.5 to 9 times the IR value, and the instantaneous short-circuit protection (II) is fixed at 10 times the In value. This model includes N-conductor protection and ground-fault protection, enhancing safety and preventing damage from earth leakage currents. It does not include an auxiliary release or auxiliary/alarm switch, simplifying the design for applications where these features are not required. This circuit breaker is suitable for systems requiring dependable and precise protection against electrical faults.
