The YCS8-I+II 40PV 2P DC600 surge protective device is engineered for photovoltaic power generation systems, offering robust protection against surge overvoltages caused by lightning strikes or grid disturbances.
Utilizing zinc oxide technology, it responds in nanoseconds (≤25ns) to divert surges safely to ground, protecting sensitive electrical equipment. It supports both Class I (10/350 μs) and Class II (8/20 μs) waveforms, with a voltage protection level Up ≤ 1.5kV and maximum discharge current of 40kA.
Its modular and pluggable design allows easy maintenance, with a color-coded status window (green for normal, red for fault). Optional remote signal contacts and dual thermal disconnectors enhance reliability. Ideal for PV combiner boxes, distribution cabinets, and DC-side lightning protection.
