MICO
General
MICO is an over current protection device to monitor the circuit of 24 V SELV or
PELV (IEC 364-4-41).
Major norm requirements for electronical machines and plants are:
Fire protection EN 60950-1
Defineable voltage condition EN 61131-2
Secured and reproduceable condition EN 61131-1
When using primary switched power supplies with conventional protection cable
failure or short-circuit can break into supply voltage. Current circuit which are
connected to the power supplies will break down. Troubleshooting takes time. The
overload element needs to be released to prevent the risk of fire. MICO keeps
availability active. Voltage break downs can be avoided.
Note:
An optimized protection for wires can be achieved. The longest cable
and the smallest cable cross-section has to be considered during the
test.
