Product description

　　ArTu low-voltage switchgear is a new type of low-voltage fixed-separated plug-in switchgear developed and developed by ABB Electric （China） Investment Co., Ltd. in cooperation with Swiss ABB Electric （China） Investment Co., Ltd. on the basis of extensively absorbing the advantages of similar products at home and abroad. The system with AC 50Hz and rated working voltage of 690V and below can fully meet the requirements of various types of applications in the market. As a control device for various power generation, transmission, distribution, power conversion and power consumption, it can be widely used in enterprises, buildings and buildings. In low-voltage power distribution systems such as hotels and municipal construction.

　　The switchgear is fully in line with the national standard GB7251 and the international standard lEC60439-1.

 

　　Features

　　The ArTu low-voltage switchgear is a new integrated power distribution system that can be used at various capacity levels up to 4000A maximum rated current. It can be either fixed or plug-in.

　　According to the characteristics of circuit breakers and components such as ABB's Megamax F, Emax, Isomax S, Tmax, etc., they are combined into functional units, which have excellent technical performance, safety and reliability, and reduce failure.

　　It can form the standard unit module structure of protection, operation, conversion and control, which can be assembled by customers at will. The number of single cabinet circuits can be up to 18 pieces.

　　The isolation between the zones and the isolation between the incoming and outgoing lines of the functional units are used to effectively enhance the safety protection performance. Form 2, Form 3, up to form 4 internal isolation forms are available.

　　K-shaped profiles meet the requirements of various structural forms, protection levels and use environments. The skeleton has a hole with a modulus of 25 mm and can be expanded for various purposes.

　　High technical performance: The main parameters are at the international leading level.

 

　　Normal use environmental conditions

　　Ambient air temperature: -5 °C ~ +40 °C, the average temperature within 24h should not exceed +35 °C.

　　Relative humidity: at a maximum temperature of +40 ° C, the relative humidity must not exceed 50%, at lower temperatures, allow a relatively large relative temperature, such as 90% at +20 c ° C, but considering the temperature change, it is possible The effect of condensation will be produced by chance.

　　Pollution degree: level 3

　　Installed indoors. The altitude does not exceed 2000 meters.

　　The equipment is installed in a location free of explosion hazard, chemical corrosion and severe vibration.

　　Overvoltage category: III

　　Exceeding the above conditions of use, when the user has special requirements, it can be specially negotiated with the manufacturer.
