3VL4740-1AA34-0AA0 SIEMENS - REF

The 3VL4740-1AA34-0AA0 is a robust 3-pole circuit breaker from Siemens' VL series, designed for reliable circuit protection without an overcurrent release. This model, a VL 400N, offers standard switching capacity, making it suitable for a variety of industrial applications. It boasts an ultimate breaking capacity (Icu) of 45kA at 415V AC, ensuring effective protection against short-circuit currents. The circuit breaker is configured for a rated current (In) of less than 400A, providing ample capacity for demanding electrical loads. This particular model does not include an auxiliary release, simplifying its operation and integration into existing systems. Its primary function is to provide dependable circuit interruption based on manual or remote switching commands. The absence of an overcurrent release means that external protection devices are required for overload and short-circuit protection. This circuit breaker is ideal for applications where a simple, manually operated switching device with high breaking capacity is needed. Siemens' commitment to quality ensures long-lasting performance and adherence to international standards.
