CBM multi-channel electronic circuit breakers in 4- and 8-channel versions

CBM – multi-channel circuit breakers with nominal current assistants

CBM device circuit breakers with nominal current assistants

Four to eight channels can be safely protected against overload and short-circuit currents with the CBM multi-channel device circuit breakers. With the integrated nominal current assistant, 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 output via the associated LED. You can use the separate signal output for remote signaling.

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

Your advantages:

  • Easy to configure with the nominal current assistant
  • Active current limitation to improve the capacity of the upstream power supply
  • Adjustable in increments per channel: from 0.5 A to 10 A

CBMC 4-channel device circuit breaker with IO-Link communication interface

IO-Link communication for system-wide transparency

Intelligent control and comprehensive monitoring with IO-Link

The CBMC portfolio also includes versions with IO-Link interface. IO-Link enables you to fully integrate the device circuit breakers into the process monitoring and control systems. It gives you a continuous overview of process-related data, keeping you up to date any time and from anywhere.

Device circuit breaker versions equipped with status output and reset input give you more diagnostics and control options in your system. After all, this product provides the option of remotely resetting the circuit. It also makes it possible to install the device circuit breaker in locations that are difficult to access.

Another version electrically interrupts load outputs with the help of built-in relays. In this case, as opposed to other electronic circuit breakers, the protected output is not only switched to high impedance in the event of an error, but is also electrically isolated.
