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 does '1P+N' mean?
A:
1P+N means the device protects both the Live (phase) and Neutral conductors. This is the standard configuration for single-phase residential systems. It ensures complete protection against surges on both wires, including neutral-to-ground faults that can be dangerous.
Q:Why is the 18mm width important?
A:
Most distribution boards have limited space. At just 18mm wide (1 module) , this SPD takes up the same space as a standard circuit breaker. You can add surge protection to your panel without having to rearrange existing breakers or upgrade to a larger enclosure.
Q:How do I choose between 20kA and 40kA models?
A:
Consider your risk level: 20kA: Entry-level protection for low-risk areas or budget installations. Suitable for apartments or homes in urban areas with low lightning activity. 40kA: Standard protection for most residential applications. Recommended for average homes with moderate lightning risk and valuable electronics. For most homes, 40kA offers the best balance of protection and value.
Q:Where should I install this SPD in my home?
A:
For maximum protection, install it in your main distribution board as close as possible to the main incoming supply, immediately after the main circuit breaker. This protects your entire house. Use short, straight wiring (< 50cm) for best performance.
Q:Can I install this myself?
A:
We strongly recommend installation by a licensed electrician. While DIN rail mounting is simple, working inside a live distribution panel is dangerous and requires to ensure: Correct wiring and proper grounding Compliance with local electrical codes Personal safety This is not a DIY project for anyone without electrical training.
