3VL2716-2NA43-0AA0 SIEMENS

The 3VL2716-2NA43-0AA0 is a high-performance circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL series, known for its reliability and robust construction. This particular model is a 4-pole circuit breaker, making it suitable for three-phase systems with a neutral conductor. It boasts a high breaking capacity (Icu) of 70kA at 415V AC, ensuring effective protection against short-circuit currents. The circuit breaker features an Electronic Trip Unit (ETU10), providing advanced protection and control capabilities. The ETU10 includes LIN functionality and a rated current (In) of 160A. The overload protection (IR) is adjustable from 64A to 160A, allowing for precise customization to the specific load requirements. The short-circuit protection (II) ranges from 1.25 to 11 times the rated current (IN), offering comprehensive protection against various fault conditions. This model does not include an auxiliary release and is N protected. Furthermore, the ETU is communication-capable, enabling integration into a network for remote monitoring and control, but it does not include an auxiliary/alarm switch.
