Description

Reliable, versatile, and perfectly integrated Every power supply depends upon a reliable infeed of electricity. 3WL air circuit breakers reliably protect electrical installations against damage or fire as a result of short circuits, ground faults, or overload faults. 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. They have communications capability and can be easily integrated into higher-level control and energy management systems. Extremely versatile 3WL air circuit breakers switch and protect motors, capacitors, generators, transformers, busbars, and cables. The modular design and uniform accessories make it possible to flexibly adapt the circuit breakers to different applications. Versions in accordance with UL 489 are available for international use. Expandable at any time The electronic trip unit of the air circuit breakers is available in different versions. Protection, measuring, and communications functions are easy to implement, even in existing installations. A rating plug that is fast and easy to replace, for example, makes it possible to adjust the rated current without the time-consuming process of exchanging the converter. Expandable locking devices or mechanisms prevent accidental switching.
