Multi-channel electronic circuit breakers

Four to eight channels can be safely protected against overload and short-circuit currents with the CBM multi-channel device circuit breakers. Thanks to the integrated nominal current assistant, setting the right nominal current for your consumers 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. Furthermore, the separate signal output can be used for remote signaling.

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

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 output 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.

Get the best protection for your system and order device circuit breakers that are preconfigured according 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 minimum quantity of one unit.

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

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. 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.
