The CBM and CBMC multi-channel electronic circuit breakers provide greater functionality while taking up less space. Thanks to Push-in connection technology, they are particularly well suited for use in machine building and control technology.

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

CBM circuit breakers with nominal current wizard

4-channel and 8-channel CBM circuit breakers  

Multi-channel electronic circuit breakers - CBM

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.

Compact CBMC multi-channel electronic circuit breakers

Compact CBMC multi-channel electronic circuit breakers

The CBMC electronic circuit breaker is tailored precisely to your requirements: it combines a compact design and individual adjustability. The four channels can be adjusted via the LED button easily and with no need for tools.

The integrated early warning system ensures fewer failures with CBMC, too. When the set nominal current of a channel reaches 80%, a warning is issued via the associated LED.

CBMC also provides the right solution for NEC Class 2 circuits. The adjustable devices for one to four amps provide ideal protection for cables and sensors.

This means that you can easily and flexibly adjust currents, save space, and reliably protect all applications with just a single device.

Specifically tailored to your system

Configure your device circuit breakers the way you want when ordering  

CBMC: device protection specifically tailored to your system

Get the best protection for your system and order device circuit breakers that are pre-configured to your requirements. You save programming time and can install and start the product up immediately.

You decide at the time you place your order which presets you would like the device to have. Each individual nominal current is selected individually. You are also free to decide whether you would like to be able to change the preset values later or want them fixed permanently. With fixed values, the current values for each channel are even printed directly on the front. You can therefore easily see the device circuit breaker settings at any time, even once it has been installed.
Order your fully customized device circuit breaker in the quantities you want, starting from a batch quantity of just 1.

To make reordering as easy as possible, every device has an order code affixed on the side. This enables seamless reordering.

Intelligent control and comprehensive monitoring

CBMC device circuit breakers with IO-Link interface  

IO-Link communication for system-wide transparency

The CBMC portfolio also includes versions with IO-Link interface. IO-Link provides you with the capability of fully integrating the device circuit breakers into the process monitoring and control systems. This gives you continuous access to process-related data and keeps you up to date on them from anywhere.

Device circuit breaker versions equipped with status output and reset input give you more diagnostic and control options in your system. This is because this product provides the option of remotely resetting the circuit. It is therefore also 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.
