PC Class TN series Automatic Transfer Switches ( ATS )

Three section, the isolation switch electrical equipment the disconnection position over voltage, under voltage and open-phase

automatic transfer switch YES1-TN Features

1.Sufficient contact open time to avoid possible arcing during changeover. 2.Contact pressure is kept constant by leaf spring and therefore no change in contact conductivity 3.due to voltage fluctuations. 4.No operating current required after the changeover because of the mechanical latch mechanism. 5.Contacts are made from silver alloy for high resistance to burn-off. 6.Self sliding contacts clean dust and oxidation on contact each time when the contactor is operated.

Standard 1.The entire series ATS are designed and manufactured in compliance with the most commin International Standards. 2.Standard Operating Conditions 3.Ambient temperature is not higher than 40°C ~ -5°C 4.Altitutd is not over 2000meter at sea level 5.Humidity L 85%~45% 6.The abnormal site conditions(vibration, shocks, dusty air, explosive, flammable, harmful gas, vapour, oilvapour and etc) not specified the above. 7.Electrical Characteristics 8.Large current capacity with small operating current. 9.Excellent performance, closing capacity-12 times as large as rated current. 10.Suitable for emergency power supply facilities. 11."On & Off" can be made by Reliable Electromagnetic Solenoid(which are employed for the transfer/changeover system) 12.Simple Operation Sequence Diagram  

Produce featuresDouble-throw switch: Special arching chambers in the both sides isolated from each other, short arching cutting time and the low consuming contacts.Safe and reliable: Unique interlocking design and single action switch ensuring only one end to power the system.Small dimension and portable: The building block structure switch of small dimension and weight saving the installation space and reducing the costs.OFF position: Manual or automatic operation can set the switch to be on OFF position to facilitate checking the failures and ensure and ensure the safety.

Mechanical Characteristics The robust mechanical structure permits easy access to the connections and components during maintenance checkups.

1.Reliable operation using the latch mechanism. 2.Compact and light weighted Design. 3.Unprecedented minimum of dimensions 4.Simplicity for construction : handiness for inspection and maintenance. 5.Superiority of contacting capacity : new system of the movable contacting mechanism makes it stable and sturdy more against high or adnormal current. 6.Long life : No trouble will occur due to the elimination of the conductive parts, main contact enjoys long wearing by rerason of arc being directed eoward the auxiliary contact.
