Import 1000v Dc Solar Isolator Switch (Tuv) — Buy in Bulk from Supplier in China

This 1000V DC solar isolator switch, model HGN4-002GL, is engineered by Yueqing Feimai Electric for disconnecting photovoltaic arrays from inverters and grid connections during maintenance or emergency shutdowns. It is rated to switch direct current at voltages up to 1000 volts, providing a critical safety mechanism in solar power systems. The product listing references TUV certification, which buyers should verify by requesting the specific certificate and test documentation from the supplier.

The switch is built with a robust housing designed to withstand outdoor weather conditions typical of solar installations. Its compact form factor allows integration into standard PV combiner boxes and inverter enclosures. Typical DC isolators in this voltage class use silver-alloy contacts and arc-chamber geometry to suppress the sustained DC arc that occurs at high voltages; confirm the exact contact material and arc suppression method with the supplier.

Solar installers, EPC firms, and renewable energy equipment distributors across residential, commercial, and utility-scale segments use these isolators as mandatory safety disconnects. The listing mentions flexible MOQ and trade terms such as FOB and CIF, though exact figures are not published. Request pricing, minimum order quantities, lead times, and packaging specifications before placing a purchase order.

Yueqing Feimai Electric Co., Ltd. operates from Xidong Village, Liushi Town, Yueqing City, Zhejiang Province, China. The Yueqing-Liushi area is a major manufacturing base for low-voltage electrical equipment in China, with hundreds of component producers in the region. The supplier is classified as an imported-tier entity on the platform with a harbour trust tier.

The listing does not disclose the company's establishment date, production capacity, workforce size, or export destinations. It references ISO and CE certifications in the marketing copy, but these are not substantiated with certificate numbers on the page. Buyers should request copies of ISO 9001 and CE documentation, along with TUV test reports for this specific model, before qualifying the supplier.
