Moulded Case Circuit Breaker
1) NLW1(DW45) series moulded case circuit breaker is suitably used in AC 50Hz, ratedvoltage 400V and 690V and distributing systems with ratings up to 6300A forelectric power distribution and protection of circuits and power supplies againstoverload, under voltage, short circuit. Provide with intelligent protecting functionand precise selective protection, breaker can enhance the dependability of powersupply and avoid unwanted power cut2) Bus-bar insulator3) RT14 type cylindrical cape fuse, used in rated voltage AC 380V, rated currentto 63A of distribution device, and served as protection of overload & short circuit.Fuse body with electric shock is fitted in, and with fuse type indicator serves asphase fault-protection of motors4) RT16 low voltage H. R. C. fuse features of light in weight, small in size, low inpower loss and high in breaking capacity. This product has been widely usedin overload and short circuit protection of electric installation.5) DW17 is suitably used in AC 50Hz 380V, 660V and DC 440V distributing systemswith ratings up to 3900A for electric power distribution and protection of circuitsand power supplies against overload, under voltage, short circuit. In normalconditions, it is used to infrequently switch over circuits. Those with the ratings upto 1250A circuit breakers in AC 50Hz and 380V systems may used for protection ofmotors against overload and short circuit. In normal conditions, they are used toinfrequently start up motors6) DW15 Series Conventional Circuit Breaker is suitably used in AC 50Hz distributingsystems with rated current up to 4000A and rated voltage up to 1140V (ACBswith rated frame current 630A and above) or 380V (ACBs with rated frame current1000A and above) for electric power distribution and protection of power circuitsand power supplies against overload, under voltage, short circuit7) Those with rated frame current 630A and below can also be used in AC 50Hz 380Vsystems for protection of motors from overload, under voltage and short circuit.In normal conditions, it is used to infrequently switch over circuits. Those withrated frame current 630A and below can also be used to infrequently start upmotors in normal conditionsAll products conform to IEC 60947-2 and GB14048.2 standards.
