MNS series low-voltage withdrawable switchgear
Category:
Product Details
Product Introduction
The MNS low-voltage withdrawable switchgear (hereinafter referred to as switchgear) consists of two parts: the power center cabinet (PC) and the motor control center cabinet (MCC). It is suitable for AC 50-60Hz, rated operating voltage of 660V and below control and distribution systems. Used by power users such as power plants, substations, and industrial and mining enterprises, it is used for power distribution, motor control, and lighting distribution equipment for energy conversion, distribution, and control.
Product Features
● Compact structure, accommodating more functional units in a smaller space, saving user investment
● Cabinets can be arranged back-to-back, and the same cabinet can be freely combined into fixed and withdrawable types
● Strong structural versatility, flexible assembly, can be designed with corresponding protection levels according to different working and environmental requirements
● All standard modules are used, series standardization, convenient for engineering designers to select
● Unique mechanical locking mechanism design, flexible and convenient operation, no special complex tools required
● A large number of high-strength flame-retardant engineering plastic components are used, ensuring the personal safety of operators
● According to different cable exit methods, cable side exit or rear exit schemes can be selected
● High technical performance, main parameters reach the contemporary international technical level
Normal Operating Environmental Conditions
● Ambient temperature: Clean air, relative humidity not exceeding 50% at the highest temperature of +40℃, higher relative humidity is allowed at lower temperatures, for example, 90% at +20℃. The possibility of occasional dew condensation due to temperature changes should be considered.
● Altitude: Not higher than 2000m
● This device is suitable for transportation and storage processes within the temperature range of -25℃ to +55℃. It can reach 70℃ for a short period (no more than 24h). Under these extreme temperatures, the device should not suffer irreversible damage, and should be able to operate normally under normal conditions. If the above operating conditions cannot be met, it should be resolved through consultation between the user and the manufacturer.
