Phoenix Contact CBM Circuit Breakers with Nominal Current Wizard

August 19, 2019

Four to eight channels can be safely protected against overload and short-circuit currents with the CBM multi-channel circuit breakers. Thanks to the integrated nominal current wizard, setting the right nominal current for your loads is easy.The selected settings are locked electronically. This prevents the risk of unwanted incorrect settings.

The integrated early warning system ensures fewer failures. When the set nominal current of a channel reaches 80%, a warning is issued via the associated LED. Furthermore, the separate signal output can be used for remote signaling.

Active current limiting enables the optimum use of the upstream power supply. This enables the use of smaller switched-mode power supply units and prevents unwanted voltage dips.

Your advantages

  • Highly versatile, thanks to fine nominal current gradations
  • Space-saving, easy installation, thanks to the compact design and Push-in connection technology
  • Increased system safety, thanks to ability to electronically lock in the set nominal currents
  • Broad range of possible applications, thanks to the wide temperature range and high resistance to shock and vibration
