Scope of Application
DZ47-125 Miniature Circuit Breaker with protection of short circuit and overload, suitable for lighting and power distribution system and power distribution system of motor. DZ47-125 is light and beautiful, and it has functions of reliable performance, high breaking capacity and quick tripping. It is mounted on the rail. The case and component are made of impact-resistant and highly fire-retardant plastic. DZ47-125 MCB has a long service life, and is mainly used for overload and short-circuit protection in AC 50Hz/60Hz circuits with voltage of 230V for single-pole and voltage of 400V for two-pole,three-pole and four-pole, and in normal condition, DZ47 MCB can switch infrequently the electric equipments and lighting circuits. DZ47 MCB can be installed with undervoltage release, shunt release and other accessories, also used for isolating switches and under-voltage protection and remote disconnection of circuit. DZ47-125 MCB meets the standards of IEC60947-2, GB14048.2 and GB10963.
