Product Details
Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or a powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.

normal usage conditions
Voltage: The voltage continuously applied between the surge protector and the terminal block does not exceed the maximum continuous operating voltage UC.
Altitude: The installation site altitude does not exceed 2,000 meters.
Ambient air temperature: normal range -5°C~+40°C, extreme range -4C~+70°°C.
Relative humidity: should be between 30% and 90% at room temperature.
Installation conditions
1.Surge Protective Device is installed on a 35mm standard rail, and the product is installed in a distribution box, distribution cabinet or box.
2.There should be no obvious impact or vibration at the installation location.
3.The Surge Protective Device is connected by copper wires, and its cross-sectional area is: 2.5~16mm for soft wires and 2.5~25mm for hard wires. The connecting wire should be as short as possible, and the total length should be less than 0.5m. The neutral wire uses light blue wires, and the ground wire uses green and yellow (two-color) wires, with a cross-sectional area of 4mm.
4.Each pole of the Surge Protective Device must be protected. A miniature circuit breaker can be used for current protection. The breaking capacity of the miniature circuit breaker must be greater than the short-circuit current there. A fuse can also be used.

Maintenance
When the surge protective device is running, you should regularly check the working status displayed in the protection module indication window – green indicates normal working status, red indicates failure, and the protection module should be replaced immediately.
Application
Surge protective device is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a peak current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit.
