3VL1706-1EH43-0AA0 SIEMENS

The 3VL1706-1EH43-0AA0 is a four-pole circuit breaker from Siemens' VL series, designed for line protection in electrical systems. It features a standard breaking capacity (N) with an ultimate short-circuit breaking capacity (Icu) of 55kA at 415V AC. Equipped with an Electronic Trip Unit TM, this circuit breaker offers precise and reliable protection against overloads and short circuits. The rated current (In) is 63A, while the overload protection (Ir) is also set at 63A, ensuring optimal performance within specified limits. The short-circuit protection (Ii) is fixed at 600A, providing instantaneous tripping in the event of a fault. This model is specifically designed for systems where the neutral conductor is unprotected. It does not include an auxiliary release mechanism, simplifying the design and reducing potential points of failure. Furthermore, it is configured without auxiliary or alarm switches, focusing solely on core circuit protection functions. This makes it suitable for applications where remote monitoring and control are not required, offering a robust and straightforward solution for essential circuit protection needs.
