Low-Voltage Electrical Protection and Solar Equipment Manufacturer

Q: Where is your factory located?

The WTAIDQ factory is at No. 11 Xiangyang Road, Liushi Town, Yueqing City, Wenzhou, Zhejiang, China. Liushi is the largest low-voltage electrical manufacturing cluster in China, which keeps component suppliers, tooling shops and test labs within a short distance of the line. Factory visits and customer audits can be arranged through sales@wtaiele.com.

Q: What products does WTAIDQ manufacture?

WTAIDQ is an electrical protection manufacturer of AC and DC contactors (CJX2, CJX2-K, CJX2-D, CJ19 and household modular series), MCB, MCCB and smart circuit breakers, automatic transfer switches, AC and DC surge protective devices, PV fuses, solar connectors, monitoring relays, time relays and waterproof enclosures for low-voltage distribution.

Q: What can be customized on an OEM order?

On OEM contactors from this electrical protection manufacturer, the coil voltage (24 V to 380 V), contact arrangement such as 1NO+1NC, terminal and marking layout, nameplate, carton artwork, EAN codes and manuals can follow your specification. New ratings, enclosures and accessories are quoted after the outline drawing is signed.

Q: What is the MOQ for OEM and ODM orders?

MOQ depends on the product family and how far the part deviates from the catalog. Standard contactors and circuit breakers can start from a flexible trial quantity, while custom OEM or ODM parts that require new tooling need a higher volume. Send the model list and annual quantity and WTAIDQ confirms the MOQ in the quotation.

Q: Do you sign an NDA and supply samples before tooling?

Yes. WTAIDQ signs an NDA before drawings are exchanged, issues a signed outline drawing for approval, and does not cut a mould until you sign it. Catalog-based samples ship in about 7 days for selected products, so fit, finish and markings can be checked before a production order.

Q: How is pricing calculated?

WTAIDQ quotes by model, rating, volume and target market. Send your product list, voltages, required certifications and quantity to sales@wtaiele.com and the engineering team returns a quotation within 24 hours.
