3VL2712-3EJ43-0AA0 SIEMENS

The 3VL2712-3EJ43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It belongs to the VL160L series, known for its very high breaking capacity, specifically an Icu of 100kA at 415V AC. This circuit breaker features an Electronic Trip Unit TM, providing advanced protection and control capabilities. The In value is 125A, representing the rated current, while the IR setting allows for adjustable overload protection within the range of 100 to 125A. For short-circuit protection, the II setting is fixed between 625 and 1250A. Notably, this model does not include N-conductor protection, auxiliary release, or auxiliary/alarm switches, focusing on core circuit protection functions. Its high breaking capacity makes it suitable for applications where high fault currents are anticipated. The electronic trip unit enhances accuracy and provides more sophisticated protection features compared to thermal-magnetic trip units. This circuit breaker is designed to ensure reliable and effective protection of electrical circuits against overloads and short circuits.
