VS1 type VCB consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column made of epoxy resin by APG technology, therefore with high anti-creepage function. Such structure design greatly reduces the accumulation of dusts on the surface of vacuum arc- extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influences, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment. 1 - with reliable interlock functions, suitable for frequent operation 2 - low noise and energy consumed 3 - simple and robust construction. 4 - high operating reliability 5 - mechanical durability of switch : 20000 times, etc
1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h. 2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M. 3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually. 4. Installation gradient not exceed 5. 5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components. 6. Any specific requirement, consult with manufactory.
