Overview

The SIVACON 8PT-4000 low voltage switchgear is a new low voltage switchgear designed by Siemens. It is designed with circuit breaker technology, fixed mounting technology and plug-in mounting technology. The SIVACIN 8PT-4000 produced by the company as a “licensed production partner” of Siemens is suitable for low-voltage distribution systems with AC 50Hz and rated working voltages of 690V and below. As a variety of power generation, transmission, distribution, power conversion and power consumption control equipment, can be widely used in industrial and mining enterprises, building hotels, municipal construction and other low-voltage power distribution systems.

The switchgear is fully compliant with the national standard GB7251 and the international standard IEC60439-I.

 

Characteristics

◆SIVACON8PT-4000 is a switchgear that has been promoted all over the world. It can be applied to various capacity levels up to 4000A. It can be either fixed or plug-in.

◆ Each SIVACON8PT-4000 is made entirely of standardized and typical modules. All modules are in accordance with the design specifications of Siemens' evaluation indicators.

◆ It can form a combination of standard unit modules such as protection, operation, conversion and control, which can be assembled by customers at will. The number of single cabinet circuits can be up to 24 pieces. All high-quality Siemens switchgear can guarantee long service life and high operational reliability.

◆Using the isolation between the areas and the isolation between the incoming and outgoing lines of the functional units, effectively enhancing the safety protection performance. Internal isolation forms of Form 2, Form 3, and Up to Form 4 are available.

◆The frame is made of 2.5mm high-quality steel plate with a hole with a modulus of 25mm on the frame, which can be expanded for various purposes. The cable can be connected from above or below.

◆The enclosure protection grade is IP30, IP31, IP40, IP41, IP42 (naturally ventilated cabinet); IP40, IP54 (non-ventilated cabinet).

◆Light weight, high mechanical strength and assembly precision, beautiful appearance.

◆High technical performance: The main parameters have reached the international advanced level.

Normal use environmental conditions

◆The ambient air temperature is not higher than +40 ° C, not lower than -5 ° C, and its average temperature is not higher than 35 ° C within 24 h.

◆Installed indoors, the altitude does not exceed 2000 meters.

◆Atmospheric conditions: The relative humidity does not exceed 50% at the highest temperature +40 ° C, and allows higher relative humidity at lower temperatures, such as 90% at +20 ° C, but considering the temperature change, it is possible The effect of condensation can occur by chance.

◆The device is suitable for the following humidity transportation and storage process: between -25 ° C and 55 ° C, in a short time (not more than 24 h) up to +70 ° C, at these extreme temperatures, the device should not Any irreparable damage is encountered and should work properly under normal conditions.

◆The equipment is installed in a place free from explosion hazard, chemical corrosion and severe vibration.

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

 

Internal structure

The basic structure of the cabinet is composed of fixed steel profiles connected to each other and can be divided into several compartments according to requirements, namely main bus room, electrical room, cable room and horizontal wiring compartment (for connection between cabinet and cabinet) wire). The skeleton profile has a M-25mm mounting hole and the outer casing is made of 2mm steel. The user can choose the surface treatment method (powder coating, painting or galvanizing) as needed.
