MNS Low Voltage Withdrawable Switchgear

Product Introduction

MNS low-voltage withdrawable switchgear is a combined, modular, standardized, multifunctional low-voltage power distribution cabinet assembled by the factory with standard modules. It is suitable for three-phase four-wire and three-phase five-wire power systems with AC 50-60Hz and rated working voltage of 380V (660V). The maximum rated working current is up to 6300A. It is used as a low-voltage system for power distribution and motor control systems in all places requiring high reliability in power plants, substations, petrochemicals, metallurgy and steel, transportation energy, light industry and textiles, and other factories and mines, residential areas, high-rise buildings, etc.

Technical Specification

Function Configuration

In summary, MCC is the "execution layer" of motor control, emphasizing flexibility and equipment-level protection. MDB is the "hub" of the power distribution system, focusing on the overall reliability and scalability of power distribution. The application of withdrawable design in both significantly improves maintenance efficiency and system availability, especially suitable for industrial environments with high continuous production requirements.

Features and Advantages

●Compact design: a small space can accommodate more functional units and has high flexibility. Auxiliary circuit scheme number
●Strong structural versatility and flexible assembly: C-shaped profiles with a module of 25mm can meet the requirements of various structural forms, protection levels and use environments, and various models and specifications of components can be installed in the cabinet.
●Adopting standard module design: It can be composed of standard units such as protection, operation, conversion, control, regulation, testing, indication, etc. Users can assemble them as needed to form fixed partition units or drawer units.
●According to different electrical equipment, various types of feeder units can be installed in the same cabinet or the same cabinet. For example, the feeder circuit and the motor control circuit can be mixed together.
●It can provide high standards of reliability and safety. The humanized design strengthens the protection required for personal and equipment safety.
●MNS is a full range of low-voltage switchgear with high technical performance, suitable for low-voltage systems below 6300A.
●Compressed site: The high degree of three-ization can greatly compress the storage and transportation of prefabricated sites.

Application

◊Industrial field
Used in factories, workshops, petrochemicals and other places, providing flexible power distribution and protection for motors, production lines and other equipment, adapting to frequent start-stop and high load requirements.

◊Commercial buildings
Centralized power distribution in office buildings, shopping malls, hotels and other places, supporting air conditioning, lighting and weak current systems, modular design facilitates expansion and maintenance.

◊Infrastructure
Applied to key facilities such as airports, subways, hospitals, etc., to ensure continuous power supply for primary loads such as fire protection and emergency lighting, with high stability.

◊Data Center
Provide reliable power distribution for precision equipment such as servers and UPS, and the drawer unit can be quickly replaced to reduce the risk of downtime.
