L7 miniature circuit breaker have protective function as shortage as overload, and are used in lighting distribution system in industry, commerce, dwelling and protect fractional electric motors. And they also have many merits of high protective grade (up to IP20), high break capacity (up to 10KA), reliable sensitive action, convenient, multipole assembling, long life etc.
They are mainly adapted to the circuit of single pole 230VAC, double, three, four pole 230/400VAC, 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.
