SPD

Application range:

LDY-20C surge protective device series are applied to equipotential bonding of the main low voltage distribution boxes in the building, providing overvoltage protection arising from the class C lightning strike to power supply system or misoperation. (Option from standard IEC61643- 1 and GB50343).

 

Main Feature:

  1. Plug and play design, live-wire replacement, easy maintenance;
  2. Build-in temperature control circuit breaker, high security performance;
  3. Green light in notice window indicates normal; red indicates broken, replacement notice, which is clear and easy distinguished;
  4. Optional telesignalling monitoring interface, realizable remote monitoring;
  5. External bus-bar wire, single module free assembled, easy project construction;
  6. Assembled 1P, 1P+N, 2P, 3P, 3P+N, 4P etc modes, applied to various electric network systems.
