MNS Low-Voltage抽出式Switchgear

Product Overview

This series of low-voltage drawer-type switchgear is a modular type cabinet assembled (FBA) at the factory, with technology that has reached international standards at the end of the 1990s.

This series of low-voltage extraction-type switchgear is used for power system distribution equipment in electrical power plants, sub-stations, petrochemical, metallurgical rolling, transportation energy, light industry and textile enterprises, residential communities, high-rise buildings, and other places. It is designed for converting, distributing, and controlling electrical energy in AC power systems with a rated working voltage of 660V and below, at a frequency of 50~60Hz.

This unit conforms to the national professional standards GB7251.1 "Low-voltage Switchgear and Controlgear" and JB/T9961 "Low-voltage抽出式Switchgear and Controlgear", as well as international professional standards such as IEC439-1 and VDE0660, Part 5.

Normal operating conditions

The surrounding air temperature should not exceed +40°C, and the low pressure should not be below +5°C. Additionally, the average temperature within a 24-hour period should not exceed +35°C.

2. Atmospheric Conditions: Air must be clean, with relative humidity not exceeding 50% at +40°C, allowing higher relative humidity at lower temperatures, such as 90% at +20°C. However, temperature variations should be considered as condensation may occasionally occur.

3. Altitude not exceeding 2,000m.

4. This device is suitable for transportation and storage at temperatures ranging from -25°C to +55°C. It can briefly reach +70°C within a short period (not exceeding 24 hours). Under these extreme temperatures, the device should not sustain any irreparable damage and should operate normally under normal conditions.

5. In the event that the aforementioned usage conditions cannot be met, the matter should be协商 resolved between the user and the manufacturer.

6. A separate technical agreement must be signed when this device is used on offshore oil drilling platforms and nuclear power plants.
