Breakers (MCB DZ47)

DZ47series circuit breaker is used in lighting distribution system or motor distribution system for overload and short circuit protecting in the system. The product is neoteric in structure, light in weight, reliable and excellent in performance. Its framer and parts adopt high fire resistant and shockproof plastics. The product with long life is mainly used in AC 50/60 Hz single pole 240V or two, three, four poles up to 415V circuit for over load and short circuit protection, as well as for unfrequented switching on & off electric equipment and lighting circuit under normal condition. The product comply with GB10963.1 and IEC60898-1
