Packing & Shipping

AISIKAI supplied 18 SKT1 160A automatic transfer switches in a centralized multi-circuit ATS cabinet for an 18-villa residential project in Saint Martin.
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.
