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.
SPS IPC Drives 2017, Nuremberg, November 28, 2017
SPS IPC Drives is Europe’s leading exhibition for electrical automation, and this year the trade fair will once again focus on Industrie 4.0. Here you can experience how the trends of digital transformation, integrated energy, and energy efficiency interact – and also learn about the role of low-voltage power distribution components and systems in this field. We look forward to seeing you!
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.
