3VL2712-2EJ43-0AA0 SIEMENS

The 3VL2712-2EJ43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL160H series, known for its high breaking capacity, specifically an Icu of 70kA at 415V AC. This circuit breaker features an Electronic Trip Unit TM, providing advanced protection and control capabilities. The In=125A indicates a rated current of 125A, while the adjustable IR setting allows for overload protection within the range of 100 to 125A. For short-circuit protection, the II setting is adjustable from 625 to 1250A, ensuring rapid response to fault currents. This model is configured with N unprotected, meaning the neutral conductor is not specifically protected by the breaker's tripping mechanism. It does not include an auxiliary release, nor does it have auxiliary or alarm switches for remote indication or control. This circuit breaker is ideal for applications requiring reliable and adjustable protection against overloads and short circuits. Its high breaking capacity makes it suitable for demanding industrial and commercial environments.
