It can happen very quickly: Thoughtlessly touching a currentcarrying cable; a faulty connecting cable; or a device fault. Happy are those who have protected their electrical system with the right RCCB. In the event of damage, it is activated within a fraction of a second, breaks the circuit and thus possibly saves lives. In this way, everyday exposure to current gets considerably safer.
For new installations and extensive renovations of commercial and private electrical systems, the use of RCCBs is mandatory according to VDE 0100-410 since June 2007 anyway. This also refers to all outdoor electrical systems and electric circuits.
Our product range offers you the right RCCB solution for every field of application because - in addition to devices of type A (sensitive to pulsating currents) and type B (sensitive to universal current) for the German market - we can also deliver devices of type AC (sensitive to alternating current - not approved for Germany) for export.

VN1-40.5E medium-voltage AC vacuum circuit breaker is a new product designed by our company. The main circuit is with the solid insulated structure and uses the advanced epoxy resin sealed technology. Firstly it assembles a integrated sealed pole column with the vacuum interrupter, the main circuit, the insulated support and so on, which enhances the environment endurance of the vacuum circuit breaker.
1. The main circuit section and operating mechanism section is upper and lower arrangement, which optimize the electric field distribution, increase the insulated reliability, also reduce the circuit breaker depth direction size and reduce the matched switchgear depth greatly.
2. The live part of main circuit is cast in the epoxy resin cylinder, which make the interrupter be exempt from the environmental effect and the external mechanical force injury, also cause the circuit breaker no arc-over between phases and on the interrupter's surface and enhance the insulation of circuit breaker.
3.Current carries are fixed reliably in the position by the epoxy resin, do not need the extra fastener, reduce the number of accessories used for assembling circuit breaker pole columns, reduce the installation error and enhance the reliability of installing the circuit breaker.
4. As a result of using the sealed technology, the circuit breaker volume reduces greatly. The matched cabinet width is only 1200mm, heighten 2400mm, depth 2600mm.
5. The VN1 circuit breaker is based on the self-supporting structure of bottom plate, has overcome the primary contacts linking due to the circuit breaker submersion and also transport conveniently.
Copper concentrate is a refined product obtained from copper ores, boasting a higher purity level compared to its raw counterparts. It typically contains 25-30% copper, achieved through meticulous removal of impurities and unwanted elements �¹.
The production process involves several steps:
- Exploration: Identifying potential copper deposits through mapping, sampling, and surveys.
- Mining: Extracting copper ore through open-pit or underground mining methods.
- Crushing and Grinding: Breaking down the ore into smaller pieces to increase surface area.
- Froth Flotation: Separating copper minerals from waste rock using chemicals and air bubbles.
- Concentrate Thickening and Filtration: Refining the concentrate to remove excess water and impurities.
- Smelting: Heating the concentrate to eliminate unwanted elements and produce copper matte.
- Electro-Refining: Dissolving copper matte in an electrolyte solution and passing an electric current to produce pure copper cathodes.
Copper concentrate has various applications:
- Plumbing: Copper\'s non-toxic, non-permeable, and corrosion-resistant properties make it ideal for plumbing.
- Electrical and Communications Wiring: Copper\'s exceptional conductivity and ductility make it perfect for electrical wiring.
- Bronze Production: Copper is alloyed with tin to produce bronze, used in bearings, statues, and other applications.
- Heat Conduction: Copper\'s high heat conductivity makes it suitable for heat exchangers.
- Construction and Architecture: Copper is used in roofing, gutters, and decorative fixtures due to its corrosion resistance and adaptability.
- Transportation: Copper is used in vehicles, planes, trains, and ships due to its versatility and reliability.
Circuit breaker refers to the switching device that can close, carry and disconnect the current under normal circuit conditions, and can close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high-voltage and low-voltage boundaries is relatively vague. Generally, those above 3KV are called high-voltage appliances.
The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, and protect the power line and motor. When they have serious overload, short circuit, undervoltage and other faults, it can automatically cut off the circuit. Its function is equivalent to the combination of fuse switch and over and under heating relay. Moreover, it is generally not necessary to change the parts after breaking the fault current. At present, it has been widely used.
Power distribution is an extremely important link in the generation, transmission and use of electricity. The distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is an electrical appliance with large amount and wide range of use.
working principle
The circuit breaker is generally composed of contact system, arc extinguishing system, operating mechanism, release, shell, etc.
In case of short circuit, the magnetic field generated by large current (generally 10 to 12 times) overcomes the reaction spring, the release pulls the operating mechanism to act, and the switch trips instantaneously. In case of overload, the current increases, the calorific value intensifies, and the bimetallic sheet deforms to a certain extent to promote the action of the mechanism (the greater the current, the shorter the action time).
