Factory wholesale Gma Switchgear - MNS-(MLS) Type Low Voltage Switchgear – Xinneng Detail:

Scope of Application

MNS type low-voltage switchgear (hereinafter referred to as low-voltage switchgear) is a product that our company combines with the development trend of our country’s low-voltage switchgear, improves the selection of its electrical components and cabinet structure, and re-registers it.The electrical and mechanical properties of the product fully meet the technical requirements of the original MNS product.

This low-voltage switchgear is suitable for power systems with AC 50-60HZ and rated working voltage of 660V and below, as equipment control for power generation, power transmission, distribution, power conversion and power consumption.

In addition to general land use, this low-voltage switchgear can also be used in offshore oil drilling platforms and nuclear power plants after special treatment.

This low-voltage switchgear complies with IEC439, VDE0660 Part 5, GB7251.12-2013 “Low-voltage switchgear and control equipment Part 2: Complete power switch and control equipment” standards and JB/T9661 “Low-voltage withdrawable switchgear” industry standard.

Operating Environment Conditions

1. The ambient temperature should not be higher than +40℃, and the average temperature within 24 hours should not be higher than +35℃, and the minimum ambient temperature should not be lower than -5℃.

2. The relative humidity does not exceed 50% when the highest temperature is +40℃, and higher relative humidity is allowed at lower temperatures (for example: 90% when +20℃).

3. The altitude does not exceed 2000m.

4. It is allowed to transport and store under the temperature condition of -25℃—+50℃, and allow the temperature not to exceed +70℃ within 24 hours.

5.The earthquake intensity is less than 9 degrees.
