AI-Powered supplier vetting
SummaryThe supplier manufactures and sells electrical, security, motor-related, and household-appliance products, including distribution box fire-extinguishing devices and dual power converters. It reports 16 years of development and integrated design, mold-making, injection molding/pressing, and assembly capabilities, with flexible through full customization available. Export sales account for 51%–70% of total sales, but exporting began only one year ago and no overseas branches, agents, warehouse, showroom, or offline trade-show participation are reported. Quality staffing is inconsistently described: one quality inspector is listed in one slice, while another reports 21–30 quality-control staff; finished products are checked by packing staff. Service procedures exist in some areas but lack written records, and no overseas service infrastructure is reported. Financial figures are excluded under the privacy requirement, and the supplied financial fields are insufficient for a reliable credibility judgment. No...
Supplier typeThe supplier is presented as a manufacturer and seller of electrical accessories, security equipment, motors/components, and household appliances. Its described integrated manufacturing model covers design, mold making, injection molding or pressing, and assembly, indicating a manufacturing-oriented supplier rather than a pure trading company.
After-Sales capabilityThe supplier reports procedures for corrective and preventive actions and customer complaints, but no written records are maintained; its service-capability assessment also has no written procedures or followed records. It has no overseas warehouse, showroom, agent, branch, or overseas service country listed, indicating limited documented after-sales infrastructure.
Production capacityThe supplier reports 16 years of development and integrated design, mold making, injection molding or pressing, and assembly, alongside manufacturing activities covering electrical, security, motor-related, and household-appliance products. However, the stated annual production output is below the supplied threshold, so production scale is not clearly strong.
Customization capabilityCustomization is explicitly offered across minor customization, flexible customization, and full customization. The integrated design, mold-making, molding or pressing, and assembly capabilities further support the supplier’s ability to execute customized products.
Product Q&A
Q:What voltage ranges does this protector support?
A:
It supports 230V AC systems (230V-300V over-voltage, 170V-230V under-voltage) and 110V AC systems (120V-150V over-voltage, 90V-120V under-voltage).
Q:Can I customize the trip thresholds?
A:
Yes, the device is fully programmable, allowing you to set specific over-voltage, under-voltage, and over-current trip points.
Q:How does the device prevent nuisance tripping?
A:
It features adjustable trip delays (0.1-10s) and restart delays (1-300s) to ignore brief fluctuations and protect compressors from short-cycling.
Q:What current ratings are available?
A:
The protector is available in 40A, 63A, and 80A models to match different single-phase load requirements.
Q:Is the reset mode automatic or manual?
A:
You can select either automatic reset (restores power when conditions normalize) or manual reset (requires a button press).
