Miniature circuit breakers are suitable for 50/60Hz AC with a rated operational; voltage of 230/400V and a rated operational current of up to 63A and used for overload protection and short circuit protection. Under normal circumstances, it can also be used for less frequent operational conversion.

 APPLICATION

To protect the electrical distribution systems and electrical devices against short-circuit (if the defect has
been caused by failure or incorrect connection) and to protect the electrical distribution system against
overload(if the circuit has not been damaged but an extreme thermal overload occurred which could
damage the wiring).
Suitable especially for common installation into switchboards and switching points of low-voltage
end circuits. It is designed mostly for alternating current but they can be used also for direct current
for which the reduction of short-circuit resistance by approx. about 20% has to be taken into account
(because of a higher stress of contacts).
Manufacturing in accordance with a particular european standard EN60898, they are able to comply with
any design requirements for arrangement of MCB’s with regard to the selectivity and requirements for
individual characteristics B, C and D.
Can be mutually interconnected by means of single-pole to four-poles interconnecting forked and
reed(rack) strips.
