3VL1702-2EA43-0AA0 SIEMENS

The 3VL1702-2EA43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for reliable line protection in electrical systems. It belongs to the VL160X series, known for its high breaking capacity. This particular model boasts an Icu (ultimate short-circuit breaking capacity) of 70kA at 415V AC, ensuring effective protection against high-fault currents. The breaker is equipped with an Electronic Trip Unit TM, providing precise and adjustable protection characteristics. The rated current (In) is 20A, with an adjustable overload protection (Ir) also set at 20A. For short-circuit protection, the instantaneous tripping current (Ii) is fixed at 300A. Notably, this circuit breaker features N-conductor protection, enhancing safety and preventing neutral-related issues. It does not include an auxiliary release, simplifying the design and reducing potential points of failure. Furthermore, it is configured without auxiliary or alarm switches, focusing on core circuit protection functionality. This makes it suitable for applications where basic, dependable protection is required without the need for remote signaling or control.
