SPD surge arrester/surge protective device/

surge protector 5KA

 The surge arrestor consists of a semi-conductor valve element that opens at certain conditions At normal conditions of the system,the surge arrestor has infinitely high resisance between the protected conductors and earthing circuit.At voltage increase due to atmospheric nature or system failure,the valve element opens and leads the excessive voltage to the grounded circuit. After reversion of the normal voltage the valve element closes.The arrestor can endure high momentary overloading

  Functions

protection of heavy-loaded electrical circuits from overloadused to protect not only particular consumers/circuits,but also the whole panelremarkable with high reliability of current characteristicscontrol:automatic switching off at exit failure and recovery after eliminating th danger
