Feature(may vary by option.)
●Dual power automatic transfer switch is made of flame-retardant PC material with excellent insulation and high temperature resistance and silver contacts to prevent aging, easy to install and maintain
●Automatic transfer switch can be operated automatically or manually to ensure power continuity, compact structure, and reliable transmission
●Constant Power Supply: Automatic switching switch is activated, and the standby power supply will work immediately in the event of an abnormal power supply to ensure the power continuous
●When normal power is on, it will automatically switch from backup power to normal power supply
●Widely used: automatic transfer switch is anti-interference, self-throwing and self-repeating type and used in various scenarios, family, shopping centers, factories, laboratories, farms, etc
[4 125a]
Description
<;80ms etc. In addition, the main contact system is SPDT (V-type) construction, so there are no two power sources connected at the same time even in emergencies.
Scope of Application
The products rated insulation voltage is 690V, the rated frequency is 50/60Hz, the rated voltage is AC 400V, the rated current is 10A to 125A. This product is primarily used to convert emergency power systems between two power supplies to ensure that critical loads are continuously and reliable. Mainly used for nationally designated first current, such as skyscrapers, post offices, firefighters, coal and marine, chemical metallurgy, industrial production lines, medical hygiene, military facilities, and other situations where a constant supply of normal power is required.
Application conditions
Ambient Temperature: Upper limit is less than +55, Lower limit is -25 or above, Maximum average day temperature is less than +35, Relative humidity is less than 90%. If the ambient temperature exceeds +55 degrees or less than -25 degrees Celsius, the user should negotiate with the manufacturer. The height of the installation location should be less than 2,000 meters. The level of contamination for the installation is III. Installation classification is as follows: be III. The main loop has an AC 33B (6le), and the motor is a mixed load. Installation conditions: The switch body can be positioned vertically or horizontally, and the installation slope should be less than ±22.5°. The controller is panel mounted. Flashover distance: For AC voltage 400V, the flashover distance is 80mm, and 100mm for AC voltage 690V.
