Low Voltage Switchgear

MNS Low-Voltage Switchgear Cabinet

Product Overview

Low Voltage MNS Series

Product Overview
MNS low-voltage switchgear is a core piece of equipment in modern low-voltage power distribution systems, integrating power conversion, distribution, control, protection, and monitoring. It supports prefabrication and assembly, and units can be removed for line maintenance. The cabinet protection rating reaches IP30~IP40. With a rated voltage ≤690V and current up to 6300A, it features power distribution, fault protection, and intelligent monitoring functions, and is widely used in industrial, commercial buildings, infrastructure, and new energy fields, adaptable to various installation scenarios.

Range of Application

Its applications cover multiple core scenarios: in the industrial sector, it includes intelligent manufacturing, ports and wharves, and grain and oil processing; in commercial and public buildings, it covers places with extremely high requirements for power supply stability, such as hospitals, office buildings, and convention centers; in infrastructure, it can be adapted to urban rail transit, municipal water and power supply, and highway service areas; in the new energy sector, it is suitable for centralized photovoltaic power stations, distributed energy storage systems, and electric vehicle charging stations; in addition, it can also be used in special scenarios such as data center UPS power distribution and military-related classified locations.

Operating conditions

● Ambient Temperature: -5°C to +40°C, with a 24-hour average ≤+35°C.

● Atmospheric Conditions: Clean air with relative humidity ≤50% at +40°C. Higher humidity is permitted at lower temperatures (e.g., 90% at +20°C), but temperature variations may occasionally cause condensation.

● Altitude: ≤2000m.

● Transport & Storage Temperature: -25°C to +55°C, with short-term (≤24h) peaks up to +70°C. The equipment shall sustain no irrecoverable damage at these limits and shall operate normally under standard conditions.

Note: For applications exceeding the above conditions, please consult our company for customization.
