Type 2 Class II 20kA 1P 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.
Installation:
• The line of surge arresters includes a full range of compact protectors for installation on DIN rail
• When the fault indication window turns from green to red please replace the cartridge as soon as possible
• After the installation is complete, check that the protection unit is plug in place, close the automatic circuit breaker (fuse) switch, check the working status is normal.
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.
We can provide products with the same parameters as citel spd catalog and eaton spd surge protection device.
