3VL1702-1DD33-0AA0 SIEMENS

The 3VL1702-1DD33-0AA0 Siemens circuit breaker is a robust and reliable 3-pole device designed for line protection in electrical systems. It falls under the VL160X N frame size, indicating its physical dimensions and mounting characteristics. This circuit breaker boasts a standard breaking capacity (Icu) of 55kA at 415V AC, ensuring effective interruption of fault currents. Equipped with a Trip Unit TM, it provides comprehensive protection features, including adjustable overload protection (Ir) ranging from 16A to 20A, allowing customization based on specific load requirements. The instantaneous short-circuit protection (II) is fixed at 300A, offering rapid response to high-current faults. This model is specifically configured for line protection applications. It lacks an auxiliary release mechanism, simplifying its operation and reducing potential points of failure. Furthermore, it does not include an auxiliary/alarm switch, focusing solely on core circuit protection functionality. The In=20A denotes the rated current. This circuit breaker is suitable for diverse industrial and commercial applications where reliable overcurrent and short-circuit protection is essential.
