TXJQ3 Electrical Isolation Switch
Scope of Application
TXJQ3 Electrical Isolation Switch is used for AC 50 / 60Hz, rated voltage 230-400V , 63A to 125A 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.
Use environment and working conditions
◆ Ambient air temperature: -5 ℃ ~ +40 ℃, the average temperature does not exceed +35 ℃.
◆ Altitude: not more than 2000m.
