Single-pole surge arrester / type 1:CPT PSC1 series is a set of Type 1+2 surge protective device that is intended for use against transient voltage rating within single-phase TT and TN-S electrical power network system. It functions with 12.5 to 25 kA electrical current rating for the limp setup, and 60 to 65 kA for the lmax.
Single-pole surge arrester / type 1:It belongs to the category of IEC / EN / VDE: Class I / Type 1 / B+C. It is an overvoltage surge protective device which has been developed for the purpose of offering protection against partial direct and indirect lightning discharges and also for providing protection in zones 0A-1.
Surge arrester Type-1 for DIN rail:The surge arrestor is made up of a semi-conductor valve element that only opens at specific conditions. It has a relatively high resistance between the protected conductors and earthing circuit under normal conditions. Voltage increase due to pneumatic environments or system crash, the valve element opens and directs the excess voltage to the grounded circuit.
