Overview
The MNS low-voltage withdrawable switchgear is an advanced product developed based on the improved design of the MNS-type switchgear from Switzerland's ABB. The product complies with IEC60439-1, GB7251, JB/T9661-1999, and other standards. This equipment is suitable for power supply and distribution systems with a rated working voltage of up to 690V and a 50 (60) Hz AC frequency. It is widely used in various industries, mining enterprises, chemical industries, construction, municipal construction, and other fields for power distribution and control.
Normal Operating Environmental Conditions
The ambient air temperature should not exceed +40°C or fall below -5°C, with an average temperature over 24 hours not exceeding +35°C.
Weather conditions should be clean, with a relative humidity not exceeding 50% at a maximum temperature of +40°C. At lower temperatures, higher relative humidity is allowed, such as up to 90% at +20°C, but occasional mild condensation may occur due to temperature changes.
Altitude should not exceed 2000 meters.
The temperature range during transportation and storage of this equipment is -25°C to +55°C, with short-term exposure to up to +70°C (not exceeding 24 hours). The equipment should not suffer irreparable damage under these extreme temperatures and should operate normally under standard conditions.
If the above operating conditions cannot be met, solutions should be negotiated between the user and the manufacturer.
