Generator Transfer Switch Dual Power Automatic Transfer Switch Load Isolation Actuating Switch AC 400V (125A) Reliable: The load isolation actuating switch is equipped with a mechanical interlock device to ensure the reliable operation of the main and standby power supplies without mutual interference.4 Operation Functions: This switch has 4 operation functions, emergency manual operation, electric remote control operation, emergency disconnection operation under automatic control, and automatic control operation.Multi : The switch supports multiple functions, including short circuit, overload, phase loss and undervoltage , which is and reliable.Applicable Scenarios: The switch can be used in homes and public places, especially in office buildings and public places that need fire .Advanced Technology: Double row composite contacts, horizontal pull structure, micro motor advanced energy storage and microelectronic control technology are adopted to basically realize no arc crossing. Specification: Item Type: Generator Transfer Switch Material: PC Rated Working Voltage: AC400V Control Voltage: 220V Rated Isolation Voltage Ui: 1000V Rated Impulse Withstand Voltage Uimp: 6KV Rated Short Time Withstand Voltage: 5kA Usage Category: AC 33B Rated Production Capacity: 10Ie Rated Breaking Capacity: 10Ie Rated Power: 50, 60HZ Grade: PC Working Temperature: - 20 to 45 ℃ (24h average value shall not exceed 35 ℃) Operating Humidity: The average humidity at 40 ℃ shall not exceed 50%, and no condensation is allowed How to Use: 1. Electric key lock: It controls the control switch inside the line power supply. When the electric lock is opened, the switch can be operated automatically by remote control, and then the electric lock is closed. The switch can only be operated through the handle. 2. Operating handle: When operating the switch, the electric lock must be closed. 3. Mechanical padlock: during maintenance, first use the operating handle to turn the switch to position 0, then pull the padlock mechanism and close the padlock to carry out maintenance: (Pulling the padlock of the mechanism will cut off the power supply of the internal control power switch, and the switch cannot be in the electric position or driven manually.) 4. Position indication: indicates the position of the working area of the switch (I, 0, II) 5. Control voltage: switch control voltage class 220VAC. 6. Switch body: the front part is line I, connected to mains; The rear is wire II, connected to emergency power supply.
