Switching Surge Protection Devices

• MOV based SPDs meets requirement of IEC61643-1

• TD technology with thermal disconnect

• Class C devices, suitable for protection against switching surges 8/20uSec , 150kA

• Large range – Suitable for operation on L-L, L-N, L-PE, N-E

• Effective equipotential bonding , clamps the voltage to lower level seen by equipment thus protecting equipment

• For better system protection, should be used in cascading scheme with class B and fine protection class, class D devices

• DIN rail mounted
