3VL6780-1TE46-0AA0 SIEMENS

The 3VL6780-1TE46-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It features a standard breaking capacity (Icu) of 55kA at 415V AC, ensuring effective interruption of fault currents. Equipped with an ETU20 trip unit, this circuit breaker offers comprehensive protection and control capabilities. The rated current (In) is 800A, with an adjustable overload protection range (IR) from 320A to 800A, allowing for precise customization to specific load requirements. The short-circuit protection (ISD) can be set from 1.5 to 7 times the IR value, providing flexibility in managing short-circuit events. Additionally, the instantaneous short-circuit protection (II) is fixed at 8 times the In value for rapid response to high-level faults. This model is configured with an unprotected neutral (N) and does not include an auxiliary release, simplifying its design and operation. It also lacks auxiliary/alarm switches, focusing on core circuit protection functions. The VL800N series is known for its dependability and suitability for a wide range of industrial and commercial applications where consistent performance is critical.
