MNS/GCK/GCS Low-Voltage Withdrawable Switchgear

Overview

Low-voltage withdrawable switchgear is key equipment for electrical power distribution and control. It is designed for low-voltage AC power distribution systems with a frequency of 50 Hz and a rated voltage of up to 400 V.

Product Characteristics

1.Withdrawable Functional Unit Design

The main functional units, such as circuit breakers and contactors, use standardized withdrawable modules and support hot-swapping. They can be quickly replaced or serviced without interrupting power, significantly reducing downtime.Each withdrawable unit is equipped with mechanical and electrical interlocking devices to ensure safe operation and prevent incorrect operation and accidental access to energized parts.

2.High Integration and Expandability

The enclosure adopts a modular segmented structure, allowing flexible configuration of multiple feeder circuits. Capacity and functional units, such as metering and monitoring modules, can be expanded according to application requirements.The standardized interface design is compatible with components from major mainstream manufacturers, reducing the cost of future upgrades.

3.Degree of Protection

The enclosure provides a degree of protection of IP30/IP40, with higher IP ratings available upon request, providing protection against the ingress of solid foreign objects and water in accordance with the specified IP rating.The internal compartmentalized design provides physical segregation between functional units and helps reduce the risk of arc propagation.

4.Core Advantages

Efficient operation and maintenance: Clear position indication shows the status of each withdrawable unit, including the Connected, Test, and Disconnected positions. The system supports online monitoring and remote control, improving operation and maintenance efficiency.High reliability: Designed and verified in accordance with IEC 61439, the switchgear provides a rated short-time withstand current of up to 50 kA for 1 s, ensuring reliable and stable system operation.Energy efficiency and environmental protection: Optimized copper busbar layout and thermal management help reduce energy consumption. The system supports intelligent power management and contributes to green and low-carbon development.
