Description Heart of the electrical power distribution 3WL air circuit breakers are used as incoming-feeder, coupler, and outgoing-feeder circuit breakers in electrical systems in industry, buildings, and infrastructure applications. Low-voltage components Components for consistent, safe, and intelligent low-voltage power distribution and electrical installation. Extremely versatile 3WL air circuit breakers switch and protect motors, capacitors, generators, transformers, busbars, and cables.

Expandable locking devices or mechanisms prevent accidental switching.

Siemens Industry Online Support. Every power supply depends upon a reliable infeed of electricity. The most important functions of powerconfig are also available in the TIA Portal — and thus directly integrated in the industrial automation environment. The PC-based eut45b makes the parameterization of the devices easier, which gives rise to considerable time savings, particularly when several devices have to be set up. Device data can be stored on a project-oriented basis, and all available parameters are clearly presented — including plausibility testing of the inputs.

The modular portfolio offers flexibility and provides for easy assembly and subsequent adjustment. Downloads and Support Take advantage of our services Here you will find important information, documents, and addresses relating to low-voltage power distribution and electrical installation technology. Configure your 3WL air circuit breaker 3WL configurator.

Egu45b, modular, and variable — the communications-capable 3VA siemenx case circuit breakers. The design of powerconfig is so user-friendly that no programming knowledge is necessary.
