Specification

Meba fuses MBR47 have protective function as shortage as overload, and used in lighting distribution system, industry, commerce, and protect fractional electric motors. And they also have many merits of high protective grade(up to IP20),high break capacity, reliable sensitive action, convenient, multi-pole assembling, long life etc. They are mainly adapted to the circuit of AC 50Hz,230V in single pole,400V in double, three, four poles for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.
