Q1: What is gel encapsulation and why does it matter?

A: Gel encapsulation is a process that seals the MOV chips with a special gel compound, providing excellent protection against moisture, dust, and corrosion. This makes ZY2-O series SPDs particularly suitable for humid industrial environments, outdoor PV stations, and coastal areas where traditional SPDs may fail prematurely.

Q2: What current ratings are available for ZY2-O series?

A: ZY2-O series offers the widest range of current ratings: 14D (5kA/10kA), 20D (5kA/10kA), 25D (10kA/20kA), and 34S (20kA/40kA). This allows you to select the most cost-effective option based on your specific surge risk assessment and budget.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: What colors are available for ZY2-O series?

A: ZY2-O series comes in 3 standard colors: white, orange, and red. Custom colors are available for large orders.
