YCS8-S I+I 40PV Surge Protection Device – 3 Pole, DC 1000V, Class I+II, 40kA, Modular Type

SKU: ELC2906

$32.00

High-capacity modular SPD for photovoltaic DC systems. Provides Class I and II protection with fast response and pluggable design.

Category:

The YCS8-S I+I 40PV 3P DC1000 is a three-pole surge protection device designed for photovoltaic power generation systems operating at DC 1000V. It offers dual protection—Class I (10/350μs) and Class II (8/20μs)—to safeguard against direct lightning strikes and induced surges. Built on zinc oxide varistor technology, it ensures no power frequency aftercurrent and a response time under 25ns. The pluggable modular design allows easy maintenance, while the green/red status window provides visual fault indication. A dual thermal disconnection mechanism enhances safety, and optional remote signaling contacts support system integration. Ideal for use in PV combiner boxes, distribution cabinets, and terminal equipment, it complies with IEC 61643-31 and supports maximum discharge current up to 40kA.
