Zinc Oxide Varistor
The Zinc Oxide Varistor supplied by Guangdong Foshan Kestar Electronic Co., Ltd. is a metal‑oxide semiconductor ceramic component designed for surge protection. It consists of a zinc oxide matrix doped with bismuth, praseodymium and cobalt oxides, forming a non‑linear voltage‑current characteristic. The varistor is offered in a general‑series format suitable for integration into electric arresters and power distribution devices. The supplier lists the product simply as “Zinc Oxide Varistor, General Series Metal Oxide Varistor”.
In the industry, such varistors are manufactured with disc diameters ranging from 5 mm to 30 mm and voltage classes from 250 V to 1500 V, providing reliable clamping of transient overvoltages. Typical specifications include a leakage current of less than 0.1 mA at rated voltage and a clamping voltage that is 1.5 to 2 times the nominal rating. Standard IEC 61000‑4‑2 testing ensures compliance with electromagnetic compatibility requirements. The material composition described by the supplier aligns with the conventional ZnO‑based ceramic formulations used worldwide.
These components are used by electrical equipment manufacturers, power utilities and OEMs that require protection of transformers, motor drives and control panels. Procurement is usually arranged on a bulk basis, with pricing negotiated per unit or per thousand units according to voltage class and disc size. The supplier does not publish a minimum order quantity, so interested buyers should confirm the MOQ and lead time directly. Shipping terms, incoterms and payment conditions are to be agreed with the supplier before order confirmation.
| Material composition | Zinc Oxide (ZnO) with Bismuth, Praseodymium and Cobalt oxide additives (Metal Oxide Semiconductor Ceramic) |
| Typical voltage class | typical 250 V to 1500 V |
| Typical disc diameter | typical 10 mm (range 5 mm‑30 mm) |
| Typical leakage current | typical ≤ 0.1 mA at rated voltage |
| Typical clamping voltage | typical 1.5‑2 × rated voltage |
| Typical energy rating | typical 100 J per unit |
| Typical operating temperature range | typical - 40 °C to +125 °C |
| Standard compliance | typical IEC 61000‑4‑2 |
| Typical packaging | typical bulk bag, 25 kg |
| Typical trade unit | typical unit or thousand units pricing |
Guangdong Foshan Kestar Electronic Co., Ltd. is located at No.2 Huansheng Road, Pingzhou Industrial Zone, Foshan, Guangdong 528251, China. The company is listed with a harbor trust tier on the platform, indicating a verified business registration, although its response rate is currently recorded as 0 % with no average response time reported. Kestar Electronic specialises in electronic components and offers a catalogue that includes varistors, resistors and related semiconductor parts. The supplier’s public profile does not disclose production capacity, certifications or specific quality management systems.
The listing highlights that the varistor is available as a general‑series OEM component and as a replacement part, but provides no details on batch testing or third‑party audit reports. Prospective importers should request material safety data sheets and any applicable compliance certificates directly from the company. No information is given about lead times, minimum order quantities or payment terms, so these commercial parameters must be clarified during negotiation.
Zinc Oxide Varistors, also known as Metal Oxide Varistors (MOV), are key components in electric arresters and surge protection devices for power distribution systems. These general-series MOVs provide reliable overvoltage clamping across industrial, commercial, and residential applications, protecting equipment from transient voltage spikes. Widely traded in global B2B markets, they are sourced as both OEM components and replacement parts, with bulk pricing typically negotiated per unit or per thousand units depending on voltage class and disc diameter.

Sourcing Zinc Oxide Varistor from Guangdong Foshan Kestar Electronic Co., Ltd. - China Import Guide
Before placing an order, verify that the zinc oxide composition matches the supplier’s description and request a material safety data sheet to confirm the presence of bismuth, praseodymium and cobalt additives. If your project requires compliance with specific environmental regulations, ask for any available RoHS, REACH or other certification documents. This step helps avoid unexpected conformity issues during import clearance.
Logistics for electronic components from China typically involve sea freight or air freight, with incoterms such as FOB, CIF or EXW negotiated per transaction. Because the supplier does not list lead times, request an estimated production schedule and shipping duration for the required volume. Clarify acceptable payment methods, for example letter of credit or telegraphic transfer, and any advance payment requirements before finalising the contract.
When importing varistors, consider arranging a third‑party inspection at the factory to verify dimensions, voltage class and performance parameters against the supplied data sheet. Request test reports for IEC compliance and a certificate of conformity for each batch. Ensure that the shipping documentation includes a commercial invoice, packing list and, if required, a certificate of origin to satisfy customs authorities in the destination country.
