Phoenix Contact's new CBMC electronic device circuit breaker combines a compact design with custom configurability. The multi-channel device circuit breaker reliably protects four channels from overloads and short circuits. These devices can be integrated into existing systems without having to redesign the control cabinet, thanks to their compact design. The individual power circuits can be configured using LED pushbuttons, without any tools. Thanks to the integrated electronic interlocking device, the preconfigured values are reliably protected from unwanted changes.
