FAQ
It meets international and national standards, including GB14048.2 and IEC60947.2, ensuring quality and safety across global markets.
Yes, it offers flexible mounting options, including on-line installation, to fit various electrical system layouts.
· Electrical Service Life: Up to 8,000 operations at AC400V/415V (varies by model), and 1,500 operations at AC660V/690V.
· Mechanical Service Life: Up to 40,000 operations with maintenance, and 20,000 operations without maintenance, ensuring long-term reliability.
Absolutely. Its vibration-resistant design makes it suitable for settings like manufacturing plants, mining sites, and transportation infrastructure.
For more details, please see the article: Comparison Between AISIKAI M1 M2-and M3 Series MCCB.
The Electronic MCCB with Built-in Electric Motorized Operating Mechanism solves the long-term reliability problems of traditional external motorized mechanisms, providing a more stable transmission.
The Load Isolation Switches (load disconnector) in this project provide visible isolation for maintenance, ensuring safe disconnection of the 5kV circuits during inspections and repairs to protect personnel and equipment.
Project Background:Vietnam's coastal ports and industrial parks are rapidly expanding. Due to frequent typhoons and rainy seasons, power interruptions are common. Many ports and cold chain warehouses require backup diesel generators and Automatic Transfer Switches (ATS) to ensure continuous operatio
