Purpose
The multifunctional self-resetting double display protector integrates overvoltage protection,undervoltage protectionovercurrent protection and integrated intelligent protector. When there is overvoitage, undervoltage and overcurrent solid fault in the line,this product can cut off the circuit instantly. Avoid unnecessary damage to electrical equipment.When the circuit returns to normalthe protector can automatically restore the circuit to make the electrical equipment work normally. The overvoltage value,undervoltage value, overcurrent value, circuit recovery time value and overcurrent protection reset time value of this product can be set by yourself.Adjust the corresponding parameters according to the actual local conditions and electrical usage conditions.

Features
The product fully complies with the single-phase self-resetting reclosing protector produced by the enterprise standard.
When the line has overvolage,undervoltage and overcurrent faults,the product will automatically cut off the line.When the line voltage or current returns to normal,the product will automatically restore normal power supply after the delay time set by the user,without manual operation When instantaneous or transient overvoltage occurs on the line,the protector will not malfunction.
The product will not be connected to the power source immediately when the line voltase is unstable due to some factors or the power is turned on suddenly after a sudden power failure.The delay time is set bythe user according to the local conditions.
The line voltage should not be higher than 330VAC at the highest point to prevent the product itself from being damaged due to excessive power supply voltage. If a high power supply is required for a specific occasion,please contact the manufacturer.

normal use conditions
1.The ambient temperature does not exceed +50 degrees and not lower than -10 degrees.
2.The altitude of the installation site does not exceed 2000 meters
3.Humidity: not more than 60%
4.Pollution degree 3

installation conditions
The protector can be installed in the body verticallyor horizontally,special order is reguired for special occasions.
it should be installed in a non-explosive medium,and there is no gas and conductive dust in the medium that is enough to ferment metal and damage insulation.
It should be installed in a place where there is no rain or snow.

The main technical parameters
1.Rated voltage: 220VAC 50Hz.
2.Rated current: 1A-40A or 1A-63A adjustable (default 40A or 63A)
3.Overvoltage action cut-off value: 240V-300VAC can be set (default 270VAC)
4.0vervoltage action cut-offvalue: 140V-200VAC can be set (default 170VAC)
5.Over-current action cut-offvalue:63A:1A-63Acan be set(default63A)/40A:1A-40Acan be set(default 40A)

use
After the protector is installed,the user can wire itand select a wire section that meets the standard according to the size of the current set by the protector. Note that the incoming and outgoing wires of the protector cannot be wrongly connected to avoid damage to the product or failure to power on.

Precautions
1.When performing various operations or tests,the user should follow the relevant regulations and pay attention to the following items to ensure the correct and safe use of this product.
2.According to the input and output terminals marked on the product,the correct load current should be less than the protection current value of the product)
3.The neutral line N cannot be connected incorrectly and must be connected reliably,otherwise the protector cannot work normally.
4.Before turning on the power,carefully check whether the wiring is correct.whether the load size matches the current protection value of the product,and whether the wiring screws are tightened,otherwise the product will be damaged.
5.After the product is powered on, please do not touch the live parts to avoid electric shock.
6.This product needs to cooperate with the micro circuit breaker toplay a shortcircuit protection function,otherwise the product will not be able to provide protection when the load is short-circuited.
7.Because the product has an automatic reset function.After the product is protected and activated,the load (electrical appliance) should be removed immediately.and the circuit should be checked,otherwise the product will freguently connect and disconnect the load. The load runs and damages the product or electrical appliances.
8. When the product is not used for a long time,it should be protected from moisture and dust.Before use,the product should be tested according to the above, and it can be put into use after it is normal.
9.This product has no isolation function,please disconnect the front-end circuit breaker switch when maintaining the circuit.
10.The spiritual line(N line)of this product is directly connected,and has no disconnection function.
11.This product has no over-current short-circuit breakingcapacity,please install a small circuit breaker such as DZ-47,C65 at the front end of the line as over-current protection.
12.If the actual settings are different from this manual due to productupgrades,please contact the company,product upgrades will not be notified separately.
