Application range
LDY-20C series are applied to equipotential bonding of the main low voltage distribution boxes in the building, providing overvoltage protection arising from the class3 lightning strike to power supply system or misoperation. (Option from standard IEC61643- 1 and GB50343)
Main Feature:
Plug-in type design, live-wire replacement, easy maintenance;Build-in temperature control circuit breaker, high security performance;Green light in notice window indicates normal; red indicates broken, replacement notice, which is clear and easy distinguished;Optional telesignalling monitoring interface, realizable remote monitoring;External bus-bar wire, single module free assembled, easy project construction. Assembled 1P, 1P+N, 2P, 3P, 3P+N, 4P etc modes, applied to various electric network systems.Main technical data
