ZOII ZY2-O series gel encapsulation DC surge protective device adopts separated base structure, exposed slot design, module plug-in is intuitive and visible, replacement operation is convenient. The product adopts gel encapsulation process to seal chips, with excellent moisture and corrosion resistance, adapts to harsh outdoor PV environments. Built-in thermal trip + DC arc suppression structure, effectively suppresses DC follow current, prevents fire, stable DC surge protection performance. All models are CE certified, compatible with mainstream industrial SPD standard mounting dimensions, can be directly replaced and installed without rewiring, widest range of optional current ratings, competitive pricing, it is a cost-effective choice for PV DC replacement scenarios.

Q1: How does ZY2-O DC differ from AC version?

A: In addition to the standard thermal trip protection, ZY2-O DC models include a built-in DC arc suppression structure. This is critical for DC circuits because DC arcs do not self-extinguish like AC arcs — the arc suppression prevents sustained arcing and fire hazards in PV and energy storage systems.

Q2: What voltage ratings does ZY2-O DC cover?

A: ZY2-O DC series covers 7 voltage ratings from 250V to 1500V DC: 250V, 500V, 600V, 800V, 1000V, 1200V, and 1500V, suitable for photovoltaic arrays, combiner boxes, and battery energy storage systems.Please make sure to select the appropriate components according to your actual needs. Operating beyond the marked current and voltage ranges will render the product unusable.

Q3: Is ZY2-O DC suitable for outdoor PV installations?

A: Yes. The gel encapsulation provides excellent moisture and corrosion resistance, making ZY2-O DC ideal for outdoor PV installations. However, the body protection rating is IP20, so it must be installed inside a weatherproof distribution cabinet with appropriate protection rating for outdoor use.
