ASKB1 series miniature circuit breaker(MCB for abbreviation)is a new generation of products developed by AISIKAl Electric for the latest market demands.MCB has compact main structure and small and beautiful appearance.Derived from the basic type,we provide several MCB with additional functions,e.g.,residual current type MCB,electronic over-volt-age under-voltage type MCB,prepaid type MCB.Through adjusting the internal components,we get the new series of miniature isolation switches ASKG2,which has the same outline dimensions and installation method as ASKB1,so they can be used together.
We have optimized the structure of the ASKB1 series in response to the demanding requirements of the household end market for MCB volume.We innovatively place the AC 220V fire and neutral lines in one shell to form the ASKB2 series,which achieves overload and short-circuit protection for household electricity.

ASKB1 normal protection type miniature circuit breaker has features as advanced structure,reliable perfomance,high breaking capacity,beautiful and compact appearance,etc.Shell and three parts are made of impact resistant and high flame retardant materials.
ASKB1 are suitable for AC 50Hz or 60Hz,rated operational voltage below 400V,rated current below125A.MCB are mainly used for the overload and short-circuit protection of lines and equipment in lighting and power distribution in office buildings,residences and similar buildings.Under normal conditions,MCB can also be used in infrequent on-off control of electrical devices and lighting lines.
Through adding intemal components with different functions ,we provide residual current protection type MCB,over-voltage under-voltage protection type MCB and prepaid meter special type MCB.
