Box Surge Protector SPD /Lightning Protection Box

SPD, also known as a power surge, is, as the name implies, a momentary overvoltage in excess of normal operating voltage. Essentially, a surge is a violent pulse that occurs within a few millionths of a second and can be caused by heavy equipment, short circuits, power switches or large engines. Products containing surge isolators can effectively absorb huge bursts of energy to protect connected equipment from damage.

Surge protectors are suitable for use in power supply systems with AC 50/60 Hz and a rated voltage of 220V/380V to protect against indirect and direct lightning effects or other transient overvoltage surges for surge protection requirements in domestic dwellings, the tertiary sector and industry.
The SPD is an indispensable device for the protection of electronic equipment against lightning. It serves to protect the protected equipment or system from shocks by limiting the transient overvoltage running to the power and signal transmission lines to a voltage that the equipment or system can withstand, or by discharging powerful lightning currents into the ground.
