TXJQ3 Electrical Isolation Switch

タイトルまたは説明

Scope of Application
TXJQ3 Electrical Isolation Switch is used for AC *0 / *0Hz, rated voltage ******0V , *3A to **5A of rated current in the resistance and inductive hybrid circuit, mainly for on or off in the no load conditions to connect or isolate line and power. Especially it is used for isolating the power supply effectively to prevent accidental switch-on when people check circuit , in order to ensure operational safety of maintainer, electrical isolator switch is widely used in the matching products of national agricultural network meter box and replaces the old knife switch, the installation is more convenient , appearance is more beautiful.
The electrical isolator switch is the most used in the high-voltage electrical isolator switches, as the name suggests, it is isolated from the circuit in its own working principle and structure is relatively simple, but because of the large amount of work, high work reliability , electrical isolator switch has a great effect on design and establishment and save running of substation and power plant. The main features of the disconnector has no arc extinguishing capability, only open and close circuits in the condition of no load current.

Normal working conditions and installation conditions
■ Ambient air temperature is *5℃~**0℃, relative humidity is less than *5%.
â–  The altitude of the installation site is not more than ***0 meters.
â–  No explosive hazardous media.
â–  No invasion of rain and snow in the environment.
Note: If the ambient air temperature is expected to be higher than **0℃ or lower than *5℃, the user should explain to the manufacturer.
 
Main technical parameters
â–  TXHGL load isolation switch of *3A ~ ***0A is divided into seven specifications, is the basis of modular design, have three-pole, four-pole (three-pole+neutral pole can be on or off), mainly for on and off of the circuit or electrical isolation, rated current of ***0A and above only for electrical isolation
â–  The front side is equipped with marking window indicating that the contact is on and off
â–  Can provide rear observation window according to the need, to observe directly the on-off state of contact
â–  Can be equipped with two sets of auxiliary contacts
