Product Description

Product Description

MNS series low-voltage Modular withdrawable switchgear

This series of low-voltage withdrawable switchgear is a combination cabinet type assembled by the factory using standard modules (FBA).

This switchgear is suitable for power plants, substations, petrochemicals, metallurgical steel rolling, transportation energy, light industry and textile enterprises, residential areas, high-rise buildings and other places. It is used for the conversion, distribution and control of electrical energy in power systems with AC frequency of 50-60Hz and rated working voltage of AC 660V and below.

The switchgear complies with the national professional standards GB7251.1 "Low voltage switchgear" and JB/T9961 "Low voltage withdrawable switchgear", as well as the international professional standard IEC439-1

Switch cabinet type
1. Power distribution center cabinet (PC): Emax, MT, 3WN, AH, ME series circuit breakers can be used.

2. Motor Control Center Cabinet (MCC): Assembled from large and small drawers, the main switches of each circuit adopt high breaking plastic shell circuit breakers or rotary load switches with fuses. Power factor automatic compensation cabinet (with manual, automatic, and remote power factor compensation devices)

Cabinet structure
The basic structure of the switchgear cabinet is composed of C-shaped profiles assembled together.
C-shaped profiles are made by bending steel plates with E=25mm as the modular installation hole.
All cabinet racks and inner partitions are galvanized and phosphated.
The surrounding door panels and side panels are coated with high-voltage electrostatic spraying.

Environmental Conditions

 

Normal environmental conditions for use
1.The ambient air temperature shall not exceed+40 ° C, not be lower than -5 ° C, and the average temperature within 24 hours shall not exceed+35 ºC.
2.Atmospheric conditions: The air is clean, with a relative humidity not exceeding 50% at a maximum temperature of+40 ºC C. Higher relative humidity is allowed at lower temperatures, such as 90% at+20 ºC C. However, temperature changes should be taken into account as condensation may occur accidentally.
3.The altitude shall not exceed 2000m.
4.This device is suitable for transportation and storage at temperatures ranging from -25 ° C to+55 ° C, and can reach+70 ° C in a short period of time (not exceeding 24 hours). At these extreme temperatures, the device should not suffer any irreparable damage and should be able to function normally under normal conditions.

If the above usage conditions cannot be met, it should be resolved through negotiation between the user and the manufacturer.
When this device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
