Advantages and features
• It can be adapted to a variety of complex power grid environments.
• The rated ultimate short-circuit current is as high as 180kA. When a short-circuit fault occurs in the power system, it can quickly cut off the fault current.
• The rated current of the copper busbars covers a wide range, which can meet the power transmission requirements of high-power loads.
• Highly durable, the electrical service life reaches 6,000 operations. The mechanical life reaches 10,000 times.

Question1: What is the power consumption of this device in normal operation and standby mode?
Answer: The power consumption of this device is less than 4W in normal operation mode, and less than 2W in standby mode. This low - power design helps to save energy and reduce operating costs, especially in long - term running scenarios.
Question2: What are the available communication settings for the RS485 interface?
Answer: The RS485 interface is isolated and half - duplex. It can be set with baud rates of 2400/4800/9600/19200 baud. It uses the Modbus - RTU communication protocol and has a maximum communication distance of up to 1000 meters. These settings make it highly adaptable for various communication requirements in different industrial control and monitoring systems.
Question3: Under what temperature and humidity conditions can this device work properly?
Answer: This device can operate within a temperature range of - 25°C to + 70°C and a relative humidity range of 20% to 93%. These wide - ranging working conditions enable the device to be used in diverse environmental scenarios, from cold regions to relatively hot and humid areas.
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.
