FAQ
1. What are the wiring methods for this model?
There are 4 types in total: Front panel wiring,rear panel extended wiring,plug-in front panel wiring,plug-in rear panel wiring.
2. What are the differences between thermal magnetic and electronic types?
The thermal-magnetic type is based on thermal/electromagnetic effects and is suitable for general protection; the electronic type provides more precise protection settings and more functions.
3. What protection functions does it have?
Overload protection, short circuit protection, undervoltage protection.
4. What is breaking capacity?
The maximum short-circuit current that the MCCB can safely cut off, in kA. The selection should be greater than or equal to the fault current value.

Project Upgrade in Peru: The customer replaced a disorganized and unstable electrical setup with the AISIKAI Electric adjustable MCCB solution, achieving cleaner wiring, more reliable protection, and improved system stability.
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
