Overview of the products

Power surge protectors (SPDs) are used to protect against lightning or other transient overvoltage induced surges, releasing large surge currents on the power line to the ground and limiting overvoltage. Mainly installed in various distribution cabinets (boxes) of the power supply system, acting as a role in protecting the circuit, electrical equipment, and personal safety.
