3VL1710-2EH43-0AA0 SIEMENS

The 3VL1710-2EH43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL160X series, known for its high breaking capacity. This model boasts an Icu (ultimate short-circuit breaking capacity) of 70kA at 415V AC, ensuring reliable performance under fault conditions. The Electronic Trip Unit TM, LI provides precise and adjustable protection characteristics. The In (rated current) is 100A, with an adjustable Ir (overload protection) also set at 100A. The II (short-circuit protection) is fixed at 1000A, offering immediate response to high-current faults. This circuit breaker is specifically configured with N unprotected, meaning the neutral conductor is not protected. It does not include an auxiliary release, providing a simplified design for standard applications. Furthermore, it is equipped without auxiliary/alarm switches, focusing on core circuit protection functionality. This configuration makes it suitable for applications where remote signaling or control is not required, prioritizing straightforward and dependable circuit interruption.
