NDD5-1 household line protector (hereinafter referred to as protector) is a new generation of household line protector developed according to the current state of power supply.It can play a protective role in the case of too high or too low voltage. When the mains voltage returns to normal, the protector will automatically switch on the power supply and restore the power supply, realizing automatic control;It also has the protection function of leakage (electric shock).The protector can be used alone or assembled with DZ47 (C45) to form a comprehensive line protection device with the functions of leakage, over-voltage, overload and short circuit protection, which can completely replace DZ47LE series products.The product has compact structure and beautiful appearance, and is installed with DZ47 (C45).
1. The working state of the dual-color light emitting tube on the panel indicates the protector: The power supply is normal when the indicator lights green, and the protection function starts to cut off the power supply when the indicator lights red.
2. Every time the input end of the product is connected to the power supply, the load should be sent for 1-2 minutes to prevent the compressor of the household air conditioner and refrigerator from starting and stopping frequently due to the instability of the power supply.
3. The protector only protects the electric shock between the output terminal phase line and the electrical equipment and the ground, but it cannot protect the electric shock that touches both lines N and L at the output end at the same time (it does not form a circuit with the ground). Please pay attention to the safe use of electricity.
4. After a period of new installation or operation (generally every other month), the protector shall press the leakage test button once to check whether it is working normally.
5. After the leakage protection of the protector ACTS, it is necessary to find out the cause and troubleshoot the fault before pressing the reset button to supply power to the load.
6. After the product is connected to the power supply, do not contact the live part. Please tighten the clamping wire screw before use to prevent the product from heating due to bad contact when large current passes.
7. Product wiring: N is zero line, L is fire line, please do not connect wrong.
