Type 2 Class II 20kA 1P 275V AC Surge Protection Device Application:
• They ensure protection against overvoltage conditions.
• For the protection of low voltage distribution systems against direct lightning strike into the overhead power supply line or external lightning protection system (IEC 62305).
• Surge protection devices (SPDs) are suitable for the IT, TT, TN-C, TN-S, TN-C-S power supply system of 50/60Hz, rated voltage 400V AC and below, protecting them from direct and indirect lightning impulse and other transient overvoltage.
• They are suitable for installation in secondary boards and in terminal equipment.
What is a surge protection device?
The surge protection device (SPD) is an electronic device that provides a protection for electrical equipment, communication network etc. from the effect of surges. When a current spike or voltage surge suddenly occurs in an electrical circuit or a communication line due to external interference, the SPD can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.
