The PC Class Automatic Transfer Switch (ATS) is mainly used in low voltage power distribution systems to automatically transfer loads between the normal power supply and the standby power supply, ensuring uninterrupted power supply for critical loads.The switch is designed for AC systems with rated operational voltage up to 400V, rated insulation voltage up to 690V, frequency of 50/60Hz,and rated current from 16A to 3200A. It adopts a PC class switching structure, providing safe and reliable switching performance with high short-circuit withstand capability.PC class ATS features a.mechanical interlocking mechanism to prevent simultaneous connection of two power sources, ensuring electrical safety during operation. The switching process is stable and reliable, making it suitable for frequent transfer operations under normal working conditions.The product is widely applied in power distribution systems of hospitals,data centers, commercial buildings, industrial facilities, and other places where continuous power supply is required. It can be operated automatically or manually according to system requirements.The PC Class Automatic Transfer Switch is designed and manufactured in accordance with international and national standards, including IEC 60947-6-1 and GB/T 14048.11, ensuring compliance with low voltage electrical regulations and reliable long-term operation.

Switch Structure Description：

Electrical Key Lock:

Controls the power supply of the internal control circuit of the switch. When the electrical lock is turned on, the switch can perform fully automatic operation, forced “0” position, and remote operation. When the electrical lock is turned off, the switch can only be operated manually.

Operating Handle:

When operating the switch manually with the operating handle, the electrical lock must be turned off first.

Mechanical Padlock:

A padlock mechanism specially designed for maintenance. During maintenance, turn the switch to the “0” position, then pull up the padlock mechanism and lock it with a padlock. This can prevent any accidental operation (when the padlock mechanism is pulled up, the internal control power of the switch will be cut off, and the switch cannot operate automatically, while also preventing the handle from being installed).

Indicator:

Indicates the three positions of the switch: I, 0, II.
