Generator Surge Protection
Application range
LDY-10D series are applied to equipotential bonding of the main lowvoltage distribution boxes in the building, providing overvoltageprotection arising from the class D lightning strike to powersupply system or misoperation. (Option from standard IEC61643- 1and GB50343)Main Feature:
Plug-in type design, live-wire replacement, easymaintenance;Build-in temperature control circuit breaker, highsecurity performance;Green light in notice window indicates normal;red indicates broken, replacement notice, which is clear and easydistinguished;Optional telesignalling monitoring interface,realizable remote monitoring;External bus-bar wire, single modulefree assembled, easy project construction. Assembled 1P, 1P N, 2P,3P, 3P N, 4P etc modes, applied to various electric networksystems.
