Circuit Breaker& Isolation

  Description: Voltage limiting type JU9D combined with voltage switching type JU9D is formed the Group JU9D, which is suiting to A.C 50/60 Hz , 380V and under 380V voltage, electric power system and protects all the distribution systems shocked by the thunder or surge over voltage.

  The items can switch on, load and break the current under normal conditions, using as switch disconnectors. Rated voltage: 230/400V Rated current: 40, 63, 80, 100A Pole number: 1, 2, 3, 4

  Main specification: Standard: IEC1008, GB16916, BS EN 61008 Rated Voltage(Un): 2Pole, 230V AC, 4Pole , 400V AC Rated current(In):25, 40, 63A Rated residual operating current(I△n): 30,100,300,500mA Rated residual non-operating current(1△no): 0.51△n Residual current off-time ≤0.1S Minimum value of rated making and breaking capacity (Im): 1KA Rated conditional short-circuit current (Inc): In=25,40A Inc=150A In=63A, Inc=3000A Endurance: On load: 2000 cycles off load: 2000 cycles Installation: On symmetric DIN rail

  the modular signal lamp is applicable to circuit with rated coltage 230V ~ and frequency 50/60 HZ fpr visual indication and signaling .

  Mini Circuit Breaker(MCB) is used in lighting distribution system or motor distribution system for protecting overload and short-circuit in the system. The product is novel structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly and its installation used with guide, its case and items ae adopted with high fire-resistant and shockproog plastics. The product, with long lige, is manily used in AC 50/60Hz single-pole 240V or two, three, four-pole 415V circuit for overload and short-circuit protection as well as for unfrequent on-and-off switching electric wquipment and lighting circuit in normal case. Rated voltage: 240V/415V AV Rated current (C): 1,3,5,6,10,15,16,20,25,32,40,50,60,63A (D): 1,3,5,6,10,15,16,20,25,32,40A Electric endurance no lower than 6000times Mechanical endurance not lower than 20000times
