Introduzione

FHXL-63 series is the current limiting fire alarm protector（current limiting protector）, and it is a comprehensive protector with multiple protection functions for overvoltage, undervoltage, overcurrent, leakage, temperature and smoke detection. The product has the advantages of modularization, intelligence, visualization and so on. At the same time, it supports the standard Modbus485 communication

protocol. All protection parameters such as overvoltage, undervoltage and overcurrent protection can be set according to the power demand, so as to ensure that the protector can instantly cut off the power supply when over voltage, undervoltage, overcurrent and other faults occur in the line, and the electrical equipment can be protected from damage.

The product has compact structure, beautiful appearance, and there is standard guide rail for installation.

Working conditions and current protection parameters

Tipo	FHXL-63
Current setting range	40A(2~63A)
Campo di impostazione della sovratensione	AC270V(210~300V)
Campo di impostazione della sottotensione	AC170V(80~200V)
Leakage current setting range	20mA(5~300mA)
Temperature setting range	70℃（1-150℃）

1. In case of the first normal power-on, the device automatically closes after 1s delay; and when powered on for the first time, under the conditions of overvoltage, undervoltage, overcurrent and leakage, the device will automatically open within 3 seconds;

2. When powered on for the first time, the smoke sensor needs to be heated for 60 seconds, and then the product enters the protection state. After smoke alarm occurs and the fault is removed, it is necessary to manually press the Reset key for 2 seconds, then the smoke alarm can be released.

3. Current protection parameters:

a. ≥ 1.05 times current, < 3 minutes opening.

b. ≥ 1.2 times current, setting range 1 to 120 seconds, 10 seconds by default

c. ≥ 2 times current, ≤0.2 second opening.

4. The ambient temperature shall not exceed + 40°C, it shall not be lower than-5°C; and the average temperature within 24 hours shall not exceed + 35°C; at + 40°C, the ambient air humidity shall not exceed 50%.

5. The altitude of the installation site shall not exceed 2000 meters.

6. Pollution level: III.

7. In the installation environment, there shall be no explosive dangerous medium, no corrosive and destructive gas and conductive dust, and no invasion of rain and snow.

current limiting fire alarm protector is Functions of the keys

1. Setting key: Press and hold the Setting key for 2 seconds, it enters the setting state. After entering the setting state, every time you press the key, the system will enter the next setting menu;

2. Shift key: query the current real-time operation parameters of the product. In the setting state, it has the digit shift function;

3. Data key: query the last fault information of the product and change the parameters to be set under the setting state;

4. Reset key: When the first overcurrent or leakage occurs, the product will automatically switch on after delaying the specified reset time. When the second overcurrent, leakage or fire alarm occurs, it must be confirmed that there is no fault in the circuit, then you need to manually press the Reset key to make the product switch on, and press the Reset key for 2 seconds to save and exit the setting state.
