Lightning and surge protection

Electrical and electronic equipment is indispensable in the daily activities of today’s businesses and individuals. Such devices are connected to the electricity grid, often exchanging data and signals through communication lines and are usually sensitive to disturbances. These interconnecting networks provide a propagation path for overvoltage. Protection against lightning and overvoltage not only ensures the safety of people, goods and equipment, But also ensures continuity of installation services and meet criteria of energy efficiency. Overvoltage protection extends the life of the equipment by more than 20%, which significantly reduces the volume of electronic waste. It also reduces the power consumption of the installations, all of which translates into cost savings and environmental sustainability

TYPE OF SPD-
DC SPD.

STP T2 40 PV is the series of devices that provide advanced overvoltage protection to photovoltaic systems by utilizing Mersen’s Optimized dynamic thermal disconnection system, which does Not require additional over current protection (back-up fuse) due to its high short-circuit withstand rating. These surge protective devices are suitable for all PV applications: large-scale, rooftop and self-consumption (off-grid) DC installations.
