CHENZHU REMIND YOU:
5 tips for your selection for a signal SPD
1）Maximum operating voltage Uc:
The maximum voltage of the signal circuit is less than Uc.
2）Nominal Operating Current IL
The maximum current of the circuit is less than this value.
3）Number of Wires: 2/3/4
Thermocouple is general 2-wires;
Thermal resistance is general 3-wires;
4) Other Main data:
Nominal Discharge Current In（8/20us): CHENZHU's signal SPD :C2：20kV/10kA/wire
Impulse Current Iimp（10/350us): CHENZHU's signal SPD D1：2.5kA/wire
5) If is screwable SPD, please also pay attendtion to the male thread you need.
