Circuit breaker can undergo frequent operation, has the ability of constant breaking and quick reclosing), and has reliable interlock function. Circuit breaker is front and back split charging structure, not only can be used as a fixed installation unit, but also can be assembled with chassis truck to form a handcart unit. It can be applied to a variety of loads and frequent-operation occasions and can be used in the industry and mining, enterprise, power plant and substation for control and protection of electrical installation. This product complies with the requirements of GB1984, IB3855, DL403 and IEC56. Features: 1. Technically much advanced: A. Using the most advanced and effective principle of vacuum arc interrupter, breaking capacity, closure of small value; B. High power life, breaking rated current of up to 20, 000 times the number of times, breaking the number of short-circuit current of 50 times (40kA for 30 times, 50kA for 20 times); C. A vacuum interrupter with operating mechanism arranged around a unified whole, reducing energy consumption and noise, more reliable operation; D. Compact structure, small size; 2 running on the excellent reliability: A. Design excellence in every detail the full account of the domestic conditions of use and national standards; B. Each transmission components with high wear-resistant materials, supplemented by good lubrication, long-term work without additional lubrication, no adjustment; C. Reliable interlock function, prevent all kinds of misuse of the human body is extremely safe. 3. Purchase the outstanding economy: A. The purchase of equipment cost-effective; B. Very little maintenance, greatly reducing the operating costs; C. Excellent general performance and reduce the difficulty of the project design; D. Technical performance and stability, no environmental pollution.Rated voltage12kVRated frequency50HzRated lightning impulse withstand voltage (phase-to-phase, phase-to-earth)/open contacts(75)/85kV(peak value)Rated 1 min power frequency (phase-to-phase, phase-to-earth)/between open contacts(42)/48kV(effective value)Rated operation sequenceO-t-CO-t-COType of circuit breakerRated currentRated breaking current(kA)Rated short circuit making current(peak kA)Rated short circuit duration time (s)Rated short circuit breaking time (s)Mechanical endurance (times)VS1-12630 125020/2550/634100200001250 1600 2000 250031.580450200001250 1600 2000 2500 315040100430100003150 40005012542010000    Customer ServiceIf you have any question ,please contact us, we will serve you wholeheartedly.
