The MNS type withdrawable low-voltage switchgear is developed by our company based on ABB's technology and integrating the essence of various drawer switchgears from home and abroad, with guidance and suggestions from major experts. The equipment's main feature is "safe and reliable, easy to maintain." The frame structure used in the equipment is highly flexible, allowing installation of different standard components inside the cabinet to meet various usage requirements. Since the entire system, including the electrical structure, adopts a modular design, this optimized structural design meets the requirements of various components and can comply with different working environments to achieve the corresponding protection level.
This equipment is suitable for AC 50~60Hz, rated operating voltage of 690V and below power systems, used for control of power generation, transmission, distribution, power conversion, and power consumption equipment. After special treatment, it can also be used in offshore oil platforms and nuclear power plants. The device complies with IEC439 "Low-voltage switchgear and controlgear assemblies", GB7251 "Low-voltage switchgear and controlgear assemblies", JB/T9961-99 "Low-voltage withdrawable switchgear assemblies" and other standards.Product Features:
