Miniature Circuit Breakers (MCB)
Features
MCB is applicable to electric circuit with rated voltage 230/400V, 240/415V AC, frequency 50/60Hz and rated current is up to 63A. The product provides against overload and short circuit and equipment in household and commercial installations. MCB is also used as non-frequent changeover of electric circuit.
