AC surge protective device LY1-12.5/1(S)Pluggable Single-Pole SPD,
We are a professional 50kA 1 pole AC surge protective device manufacturer, producing compact,
and reliable SPDs for single-phase 230V AC networks. As an experienced factory,
furthermore we provide OEM, wholesale, and bulk buy services to electrical wholesalers and system integrators worldwide.
moreover Built with a graphite (C) shell, rated IP65,
in addition to mounted on a 35mm DIN rail, it ensures convenient installation and high safety.
therefore Each unit is CE certified and backed by a 2-year warranty.
then We also provide OEM design and bulk order services,
after making this SPD ideal for wholesalers who require reliable,
finally cost-effective surge protection directly from the manufacturer.
