Multi-channel electronic circuit breakers CBM

Setting a circuit breaker was never so easy. With the integrated nominal current assistant, selecting the appropriate current for the connected load is incredibly easy. This makes configuration fast, convenient, and simple.

  • Easy setting with the nominal current assistant
  • Active current limitation for improved utilization of the upstream power supply
  • Adjustable in increments per channel: from 0.5 A to 10 A

Setting a CBM using the nominal current assistant by turning a potentiometer with a screwdriver

The nominal current assistant makes setting the CBM exceptionally easy. It enables optimal adaptation to the load currents. Simply turn the rotary switch until the optimum current has been found. The LED displays the ideal setting. It could not be easier to configure the ideal system protection.

Voltage limiting display of the current limitation

Active current limitation restricts short-circuit and overload currents to a value that is 1.5 to 2 times that of the nominal current. This protects the power supply against excessively high currents and prevents output voltage dips at the switched-mode power supply unit. Longer cable paths between the power supply and consumer are also possible without negatively impacting shutdown behavior.

In addition, the currents in the system are permanently monitored. The CBM distinguishes between undervoltages and overvoltages and thus increases system availability. The circuits are shut down in the event of an error in the operating voltage and the system is switched to a defined state. The error is indicated via the “DC OK” LED and signaled via the remote indication contact.

The CBM can be adjusted in precise nominal current steps. The nominal current range is 0.5 to 10 A. You can therefore adapt the channels individually to the connected end devices. You can make these settings for each individual circuit. If the utilization of an individual channel is above 80%, you will receive a message. This enables you to respond in good time to prevent a failure by making settings on the circuit breaker.
Its flexible adjustability allows one device to be used for different loads. This reduces your inventory costs and also ensures high flexibility in system planning at the same time.

One-button operation makes adjusting individual circuits easy. You can adapt the channels of the device circuit breaker individually to meet your needs, and without any tools.
The multi-functional buttons do much more than provide the option of programming the device circuit breaker, however. They also detect the operating state of the product and connected devices and indicate the status using traffic light colors. In addition, the individual channels can be switched on and off with the buttons.

Get the best protection for your system and order device circuit breakers that are preconfigured according to your requirements. This means that you save programming time and can install and start up the product 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 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 require, starting from a batch quantity of just 1.

To make reordering as easy as possible, you will find the order code on the side of every device. This makes reordering trouble-free.
