CBM multi-channel electronic device circuit breakers by Phoenix Contact:
The multi-channel electronic device circuit breaker provides protection for four or eight loads, depending on the version. The individual channels can be configured individually and have an electronic locking mechanism to prevent incorrect setting. The status of each channel is displayed directly on the device and can also be queried as group remote signalling using the connections provided for this purpose.
The multi-channel, electronic device circuit breakers are optimally suited for use in machine building, process engineering and control and systems manufacturing. The dynamic current limitation prevents interruption of the output voltage in case of error. The individual adjustability of the4 and 8 channel devices provides a convenient and space-saving solution for any application.
The multi-channel electronic device circuit breakers differentiate between three states: normal operating state, overload and short circuit. In the range between 1.1 and 1.3 times the nominal current, an overload is detected and switched off after thirty seconds for safety reasons. If the flowing current is over 1.3 times the nominal current, it is detected as a short circuit and actively limited depending on the configured current. Switching off in case of short circuit occurs after 20 milliseconds. This allows the supply voltage to remain consistent, while other loads can continue to run without interruption
Illustration of application: By using multi-channel electronic device circuit breakers, the project engineering for switchgear is significantly simpler and more easily understandable. The configurable nominal currents can be used to adjust the required protection for the load used. This makes the devices very well-suited for protecting relays, programmable controllers, motors, sensors/actuators and valves. Also, the signalling always keeps the user up-to-date about the operating state of the system. The reset input can be used to remotely switch back on paths that have been switched off.
