一、Product Overview
The DLG1 isolation switch has high dynamic thermal stability, and is mainly used as a switch in a terminal assembly for the power distribution and control loop of AC 50Hz or 60Hz and rated voltage below 400V, and also can be used to control the motor low-power electrical appliance. And lighting is widely used in industrial and mining enterprises, high-rise buildings and homes and other places
二、Second, the model and its meaning
三、Third, classification
A: According to the rated current IE: 32A, 63A, 80A. 100A, 125A
B: According to the number of poles: unipolar. Two poles. Three poles. Four poles.
四、the main technical parameters
Rated working voltage Ue: 230v (single-phase), 400V (three-phase);
Working current Ie: 32A, 63A, 80A, 100, 125;
Rated short-time withstand current: 12Ie power-on time is Is;
Rated short circuit capacity: 20Ie. Power-on time is 0.1S
Rated on and breaking capacity: 3Ie, 1.05Ue.COSφ=0.65;

Operating frequency is 120 times/hour.
五、Normal working conditions and installation conditions
1: The ambient air temperature: a 5 °C ~ +40 °C, the average value of 24h does not exceed 35 °C;
2: altitude but 2000rn
3: Atmospheric relative humidity is not more than 50 at 40°C, and the wettest month is 90%.
4: Pollution Level 2
5: Use category AC-22A;
6: Installation category I, II;
7: The installation form is installed with TH35-7.5 mounting rails. The inclination between the mounting surface and the vertical plane should not exceed 5.
六、shape and installation size
七、Structural features
The switch contact system adopts a double breakpoint precession structure, and the large current adopts two parallel parallel contacts, which increases the current capacity and fully utilizes the electric power compensation. At the same time, the handle operating mechanism utilizes the spring to realize quick pass. Broken. Overcoming the impact of the speed of manpower operation, greatly affecting the reliability of the work, the contact opening and closing state with eye-catching color mark display, can prevent misuse, improve security.
八、installation and use
A: The switch is installed vertically, the upper end is connected to the power supply, the lower end is the outlet, and the handle is pushed up to turn on and display red. Pull down to disconnect the green display, not reversed.
B: Before the electricity is turned on, it should be operated manually several times. Its mechanism should be flexible and reliable without any blockage.
九、matters needing attention
Allows the switch to switch on and off as often as necessary (including an appropriate overload), but it cannot be used to break the current of the circuit.
十、ordering instructions
When ordering, the model number, rated current, number of poles, and number of disconnectors must be specified.
For example: DLG1-125 isolation switch, rated current 63A, three pole, 500 units
It is expressed as: DLG1-125-63A-3P500 Taiwan.
