3WL Air Circuit Breakers High Quality Smart Circuit Breakers Up to 150kA 6300A

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.
