MNS type low-voltage switchgear is researched and developed by our company on the basis of improvement of component choice and cabinet structure. Meanwhile it combines with our country's development trend of low voltage switchgear. It is suitable for power plant, substation, petrochemical industry, metallurgical industry, steel rolling and so on where the electrical system is that rated working voltage is 660V and the below and the frequency is 50~60Hz as application of electricity exchange and equipment control.
This low-voltage switchgear is in accord with the fifthly part of IEC6043P VDE0660, GB7251-1991Low-voltage switchgear and control gearand JB/T9661Low-voltage withdrawable switchgear.
2 Standards and specifications

3 Working conditions
3.1 Ambient air temperature is between +40º C and -5º C, while, average temperature in 24h is no more than +35º C.
3.2 Atmospheric Conditions: Clean air, relative humidity is no more than 50% at the highest temperature +40º C, relative higher humidity is admissible at lower temperature, for example, it is 90% at +20º C. Should consider the change of temperature, there is moderate dewing in accident.
3.3 Altitude is no more than 2000m.
3.4 Pollute grade is 3.
3.5 The equipment is applied to transportation and storage process at the below temperature: Between -25º C and +55º C. It can up to be +70º C in short time (no more than 24h). At the extreme temperature, it should not be subject to unrecoverable damage. Meanwhile, it should run well at normal condition.
3.6 If the above application conditions can not be met, the user should confer with the manufacturer to solve it.
MNS type low-voltage switchgear (short as equipment) is a modularized and multifunctional low-voltage distribution cabinet. It is applied in the field of petroleum, chemical industry, metallurgical industry, industrial and mining enterprises and infrastructure which need high reliability low voltage system and distributing and motor control system. MNS is whole series low-voltage switchgear and can meet full range requirement. In the low voltage system of below 5000A, MNS can provide high standard reliability and safety. The special profile structure and connection manner and compatibility to various components can meet the requirement of harsh period and power supply continuity.
