Power distribution system handles short
circuits
Murrelektronik's two-channel MICO allows users to design a more efficient and easy-to use MICO system.
Murrelektronik has released the MICO intelligent power distribution system, which monitors current, indicates current rating and detects overloading It simplifies trouble shooting and reduces machine downtime

Easy to use interface for any automation project
The new SCADA Portal from ABB is an easy-to-use graphical interface for controlling remote processes from small, standalone applications to five clients and up to 10,000 I/O per server
Murrelektronik has supplemented the standard four-channel MICO product range with a two-channel version, which allows designing an even more efficient and easy-to use MICO system.
Power supply systems have to provide high inrush currents for the startup of an installation, while at the same time ensuring a reliable shutdown in case of short circuits or overloads.
When using only circuit breakers it is difficult to meet these two requirements in accordance with the applicable standards.

ABB's new SwitchLine range of change-over/transfer switches is designed to provide safe and reliable on-load switching between two power supplies.
Slow blow fuse characteristics can cope with high capacitive loads, however, they do not reliably react to short circuits.
If there is a failure the service technician cannot see which path shows the fault that caused the shut down.
Fast releasing circuit breakers reliably react to short circuits, but with high capacitive loads they react too fast.
MICO supports high capacitive loads and detects overloads even during running operation and safely shuts down.
MICO monitors each current channel using the selected current range.
If everything is OK, the corresponding LED lights up green.
The LED starts blinking when 90% of the maximum rating has been reached, giving a visual warning.
If the selected current range is exceeded, the current path affected will be switched off.
The LED starts blinking red.
The service technician can see at a glance where the fault occurred.
This state will be stored and maintained even if power is lost and the machine is powered up again.
MICO modules are equipped with two or four bridgeable channels, so that they can easily and quickly be connected via a bridging system.
Thanks to MICO's integrated floating alarm output the laborious connection of auxiliary contacts is unnecessary.
A group alarm can be obtained by connecting a cable to the first and final modules.
The MICO is equipped with spring clamp terminals, reducing the time required for the connection and ensuring safe contacts when faced with vibrations.
The integrated labels make identification very easy.
A system using the MICO takes up 30% less space than one using circuit breakers.
The new slim design two-channel MICO allows even more application-friendly solutions with two, six, or 10 channels connected.
The two-channel MICO allows operating at capacitive loads of up to 20000uF.
