AI-Powered supplier vetting

SummaryYueqing Greenwich Imp & Exp Co., Ltd. is identified as a China-based manufacturer/factory and limited company located in Zhejiang, with a factory in the Qiligang/Liushi area. The supplier reports ISO 9001 certification, 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. Listed production capacities are 90,000 contactors, 210,000 circuit breakers, 30,000 switches, and 60,000 relays. Its product scope centers on electrical components including MCCBs, MCBs, contactors, relays, starters, and circuit breakers. Export activity reportedly began in 2017, with 41%–50% of sales from exports and exports conducted directly or through agents. The records provide limited evidence on after-sales service, financial credibility, innovation, customization, and customer-case depth. Trade records show one transaction associated with a Kazakhstan buyer in February 2025, but monetary figures are omitted.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and Limited Company, with its head office and factory located in Zhejiang, China. However, another record describes the company nature as a trading company, indicating a mixed or potentially inconsistent classification across the available data.

CertificationsThe supplier reports holding ISO 9001 certification for its management systems. This is explicit evidence of a documented quality-management certification, although no certification scope, issuing body, or validity dates are provided.

R&D capabilityThe supplier reports 6–10 years of total R&D-engineer experience, and its company description mentions continuous improvement and innovation. These provide some positive indication of development capability, but no specific patents, proprietary products, R&D projects, or new-product examples are supplied.

Production capacityThe supplier reports 10 production lines, 6–10 quality-control staff, and stated annual capacities of 90,000 contactors, 210,000 circuit breakers, 30,000 switches, and 60,000 relays. The same capacity figures appear consistently across two records, and a physical factory location plus ISO 9001 certification are reported, supporting a positive assessment of production capability.

Product Q&A

Q:What are the main protection features?

The soft starter protects against voltage loss, undervoltage, overvoltage, over-current, overheating, phase losses, unbalance, and short circuits.

Q:What start modes are available?

It offers five modes: Ramp voltage start, Current limit start, Snap action + Ramp voltage start, Snap action + Current limit start, and Heavy load strong shock start.

Q:Is it suitable for pump applications?

Yes, it reduces hydraulic shocks, minimizes mechanical stress on the motor shaft, and prevents damage from blocked pipes or low water situations.

Q:What is the input voltage range?

It supports three-phase AC input voltages of 220V, 380V, 440V, and 660V at 50Hz or 60Hz.

Q:Can it handle heavy loads?

Yes, it includes specific modes like Snap action and Heavy load strong shock start for motors with high static friction forces.
