3VL2712-3EC43-0AA0 SIEMENS

The 3VL2712-3EC43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It is part of the VL160L series, known for its very high breaking capacity, specifically an ultimate breaking capacity (Icu) of 100kA at 415V AC. This circuit breaker features an Electronic Trip Unit TM, providing advanced protection and control capabilities. The rated current (In) is 125A, with an adjustable overload protection range (IR) from 100A to 125A, allowing for customization based on specific load requirements. For short-circuit protection, the instantaneous tripping current (II) can be set between 625A and 1250A. Notably, this model does not include N-conductor protection, an auxiliary release, or an auxiliary/alarm switch. This makes it suitable for applications where these features are not required, simplifying the installation and reducing costs. Its primary function is to safeguard electrical circuits from overloads and short circuits, ensuring the safety and reliability of the connected equipment. The 3VL2712-3EC43-0AA0 is ideal for industrial and commercial applications demanding high performance and dependable circuit protection.
