  Features   

Frequent Operation Capability

SKT1 series Automatic Transfer Swtich has the highest ATS Use Category: AC-33A, capable of frequent operation. 

AISIKAI SKT1 ATS is suitable for applications where power continuity is critical and power source switching is performed on a regular basis. 

LED Indicators for ATS Status Monitoring 

Equipped with LED indicators on the front panel, the switch provides clear visual feedback on its working conditions. This allows users to easily monitor the status of the switch at a glance,  enabling operators to quickly identify any issues and take appropriate actions.

Easy Maintenance

• Replaceable Fuses: 

We use replaceable fuses innovatively in order to simplify the maintenance procedures. 

In case of any fuse-related faults,  the process of replacing fuse is quick and straightforward, minimizing downtime.

• Modular Control Unit: 

Modular and resin-fully-sealed control unit. It features high anti-interference capability and resistance to moisture, dust, and salt spray. Supports quick plug-and-play, significantly reducing maintenance difficulty.

Well-engineered Structural Design

•  One-Piece Design on the Load Side Copper Bars: 

The load side of the SKT1 ATS features a one-piece structure, which not only simplifies wiring but also saves material costs. 

• Mechanical Interlock and Electrical Interlock: 

The combination of mechanical and electrical interlocks ensures that the Automatic Transfer Switch operates safely, ensuring a high level of safety during operation and preventing any potential hazards. 

• Three-Position(I – 0 – II) Design:

 The Zero Position, provides a safe and reliable way to cut off power during maintenance, protecting both operators and equipment.

Preium Material

• High Purity Copper Bars: 

The copper bars of the automatic transfer switch use high purity T2 copper(99.9%).

This gives our SKT1 ATS excellent electrical conductivity and durability, minimizing energy loss and extending the transfer switch's service life.

• Silver Plated Copper Bars
  

The copper bars of the automatic transfer switch are silver plated, to ensure low contact resistance, excellent conductivity, and superior anti-corrosion performance.
