Industries We Serve
From residential buildings to solar farms, data centers to industrial plants WTAIDQ delivers reliable electrical protection and power distribution solutions across every sector.
Common Electrical Protection Challenges
Most electrical failures trace back to a few root causes. We identify which ones apply to your installation before recommending hardware.
Earth Leakage & Shock
Insulation failure creates leakage current to ground endangering personnel and tripping circuits.
FIX · RCCB / RCBO / TYPE B RCD
Surge & Lightning
Transient overvoltages destroy sensitive electronics in microseconds PLCs, drives, communication gear.
FIX · SPD TYPE 1+2 / TYPE 2
Motor Start Inrush
6–8× rated current at startup stresses contactors and cables causing wear, dips, and stoppages.
FIX · MPCB / CONTACTOR / THERMAL RELAY
Three-Phase Imbalance
Uneven loading overheats neutrals, reduces motor efficiency, and wastes transformer capacity.
FIX · RCCB / RCBO / TYPE B RCD
Arc Flash Hazard
Uncontrolled arcs release explosive energy causing injury, equipment loss, and extended downtime.
FIX · SELECTIVE MCCB / ACB COORDINATION

Yes. Rated to 1500V DC per IEC 60947-2, with 6–10kA breaking capacity. Magnetic blowout arc extinguishing for reliable DC interruption. Deployed in utility-scale solar farms across Africa and Asia.
Yes. We support OEM and ODM partnerships including custom branding, packaging, labeling, and product configuration. Share your specifications, target market, and estimated volume—we will assign a project engineer and provide samples and quotation.
Our products are designed and tested to international standards including IEC 60947-2 and related regional requirements. Certifications vary by product series (e.g. CE, CB, and market-specific approvals). Tell us your destination market and we will confirm the applicable certificates for your SKU.
Standard catalog items typically ship within 2–4 weeks after order confirmation. Bulk or customized orders depend on model, quantity, and production schedule—usually 4–8 weeks. We provide a confirmed lead time with every quotation.
We accept T/T (wire transfer), L/C for qualified orders, and other trade terms agreed in the contract. Payment schedule and currency are confirmed in the proforma invoice.
We can supply test reports and certificate copies for the models you order—CE, CB, ISO 9001, and product-specific type-test documentation. Request the full certificate pack when you send your inquiry.
Standard warranty is 12–24 months from delivery date depending on product line, against manufacturing defects under normal use. Extended warranty and spare-parts support are available for project and distributor partners.
