E2R-63 Dual Power Automatic Transfer Switch
Product Details
Product Descriprion
The E2R-63 Automatic Transfer Switch (ATS) is a high-performance PC-class infrequent change-over switch designed for reliable power supply management. It features a two-station design (typically Main power supply A and Backup supply B) and is suitable for AC 50-60Hz systems with a wide rated current range of 6A to 63A. Its primary function is to automatically transfer the load from a failing main power source to the backup source in under 50 milliseconds, ensuring uninterrupted operation and effectively solving power outage troubles.
Constructed for DIN-rail mounting, this compact switch (sizes: 108x50.5x78mm for 2P, 108x82.5x78mm for 4P) operates within a temperature range of -5°C to +40°C. Key specifications include a rated impulse withstand voltage of 8kV, support for various voltages (AC110V/220V/380V/400V), and comprehensive undervoltage/over-voltage protection. It offers both automatic and manual operation modes (with safety notes for manual use) and is backed by a patented control circuit design. Professional installation and annual maintenance are recommended to ensure optimal performance and safety, making the E2R-63 an ideal choice for critical power switching applications requiring fast, automatic failover.

Working Conditions
①The operating environment temperature range is -5 °C-+40℃,and the average temperature value within 24 hours does not exceed+35°℃.The storage environment temperature range is-25C-+55℃,and can reach+70°℃in a short period of time (within 24hours).
②The altitude of the installation site shall not exceed 2000.
③The relative temperature of the air at the installation site should not exceed 50%when the surrounding air temperature is+40℃,and there can be higher relative humidity at lower temperatures.For example,when the average lowest temperature in the wettest month is+20 °℃,the average highest relative humidity in that month can reach 90%.Appropriate measures should be taken to prevent condensation caused by temperature changes.
④Pollution level 3 (with conductive pollution,or dry non-conductive pollution turned into conductive due to condensation).ATS can be installed vertically or horizontally inside the cabinet.If there are special installation requirements,please contact our company.The protection level of the product shell is IP30.
⑤Over-voltage category:Main circuit class Ⅲ;Control and auxiliary circuits Class Ⅱ.
Note
①Manual/automatic operation can ensure the on/off performance of electrical operation,but in manual operation,it cannot be guaranteed due to the different on/off speeds of the operator.Excessive loss of silver alloy may occur during manual operation.Therefore,the selector switch can only be pulled to the manual position after cutting off all power sources to check and maintain the operating system and contact information.Usually,please pull the selector switch to the electric position.When manual operation is required,pull the selector switch to the manual position.After completing the manual operation,pull the selector switch from the manual position to the automatic position.
②The control circuit TSE is immediately excited.After the conversion is completed,the internal switch will damage the coils in the control circuit,which can operate normally at 85%-110%of the rated working voltage.Low input voltage may cause the coil to heat up and burn out.
Install
Before installation and wiring,please ensure that professionals have read this manual.Before installation,please check the integrity of ATS.Then tum on the ATS with an operating handle,check the flexibility of the operating mechanism,and check the on and off status of each phase as well s the load of the normal and backup power sources.Please equip ATS with suitable circuit breakers according to the installation requirements of the power distribution system to ensure the safety of personnel and equipment.
