Short Description:

Summary

TU2 Series Surge Protective Device is suitable used for power distribution and control system with AC 50Hz and rated voltage 230V/400V.it meets the ll testing requirements of SPD, using for suppressing overvoltage impact device of transient overvoltage, discharging surge energy, thereby protecting the system circuit and equipments.

TU2 Series Surge Protective Device is suitable for classified coordination, and realizing the classification protection system (class 1,2 or 3), so that the low voltage power distribution system is more extensive and more effective protected.

Suitable range

TU2 SPD is generally parallel connected onto the front crcuit of the required protected circuit equipment as close as possble the down circuit teminal. The SPD is connected with one end of the circuit conductor (phase line L or neutral line N), and the other end of the conmecing line of equipment grounding device for the lightning equipotential connection.
