MNS Low Voltage Withdrawable Switchgear

Pino Electric, a professional low-voltage distribution equipment manufacturer, presents the PN-MNS-W MNS Low Voltage Withdrawable Switchgear—a modularly engineered solution designed for reliable power distribution, control, and protection across industrial, commercial, and infrastructure applications. Operating at AC 50/60Hz with a rated voltage range of 380V to 690V and a maximum unit rated current of 3150A, this switchgear addresses critical pain points including unplanned downtime, complex maintenance, and limited space in modern power systems. Built with galvanized steel C-profiles and high-voltage electrostatic spraying technology, every unit undergoes rigorous pre-delivery testing to ensure consistent performance under demanding operating conditions. For specialized environments such as offshore oil drilling platforms and nuclear power plants, we provide tailored technical agreements to meet unique safety and performance requirements.

Key Features That Drive Operational Efficiency

Modular & Scalable C-Profile Structure

The switchgear adopts a standardized C-profile frame with 25mm module mounting holes, enabling flexible configuration and seamless system expansion. This design simplifies on-site installation, component replacement, and future upgrades, allowing you to adapt your power distribution system to evolving production needs without full-scale reconstruction.

Comprehensive Safety Protection System

Compliant with IEC529 and DIN40050 international standards, the switchgear offers multiple protection levels: IP30 (against solids >2.5mm), IP40 (against solids >1.0mm), and custom IP54 (dust-tight and splash-proof from all directions). It is equipped with integrated short-circuit, overload, and leakage protection functions, effectively preventing equipment damage and personnel safety hazards.

Drawer-Type Independent Functional Units

Each functional unit operates as an independent withdrawable drawer, allowing maintenance and replacement without shutting down the entire power system. This design reduces unplanned downtime by up to 80%, minimizing production losses and improving overall operational efficiency.

Reliable Electrical Performance

We use premium electrical components including Emax, MT, 3WN, AH, and ME series circuit breakers for power distribution center (PC) cabinets, and high-break plastic-case circuit breakers or fuse-equipped rotary load switches for motor control center (MCC) cabinets. The main bus supports a rated peak withstand current of up to 176kA, ensuring the system can withstand instantaneous short-circuit impacts without permanent damage.

Intelligent Monitoring & Energy Efficiency

The switchgear supports intelligent monitoring and management systems, enabling real-time tracking of electrical parameters, remote fault diagnosis, and early warning alerts. Additionally, it uses eco-friendly materials and energy-saving designs to reduce power consumption and environmental impact, aligning with global green manufacturing standards.

FAQ

What is the difference between PC and MCC cabinets?

PC (Power Distribution Center) cabinets are designed for high-current main power distribution, compatible with Emax, MT, and ME series air circuit breakers. MCC (Motor Control Center) cabinets use drawer-type units for individual motor and load control, ideal for managing multiple low-to-medium current circuits.

Can the switchgear operate at altitudes above 2000m?

Standard units are rated for altitudes up to 2000m. For higher altitude installations, we can provide derated designs and additional insulation measures—please consult our technical team for a customized solution.

What are the standard cabinet dimensions?

Standard PC cabinets measure 2200mm (H) × 400-1200mm (W) × 1000mm (D), while standard MCC cabinets measure 2200mm (H) × 1000mm (W) × 600-1000mm (D). Custom dimensions are available upon request.
