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.
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.
3WL air circuit breakers are available in four sizes, each featuring a 3- and 4-pole design, and cover a power range from 630 A to 6,300 A. The modular portfolio offers flexibility and provides for easy assembly and subsequent adjustment.
3WL air circuit breakers are now also available in a particularly compact size of 0 to 1,250 A. The communications-capable switches minimize the space requirements in the switchgear. With individual electronic trip units, comprehensive internal and external accessories, and a variety of connection technologies, these can be flexibly integrated into switch boards in accordance with IEC61439-2 and incorporated into higher-level energy management systems via communications modules.
