Product details
This plug-in lightning/surge protector offers you security and protection against unexpected surges and disturbances to your network/equipment.
Product Description
SPD Surge Protective Device, Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limit instant surge voltage and discharge surge current, it at least including a non-linear component.
Selection Principle
- The continuous applied voltage on the two terminals of SPD should not more than the maximum continuous operating voltage Uc value;
- The voltage protection level Up of SPD should less than the maximum impulse withstands voltage of the protected equipment;
- As per to the different earthing system and protection mode to select the specification accordingly;
