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 benefits of using this soft starter over star/delta starters?

It reduces start current without damaging torque transients, controls the voltage ramp down for smooth stopping, and prevents load acceleration issues common in star/delta configurations.

Q:What types of motors are compatible with this device?

It is suitable for three-phase squirrel cage asynchronous motors and induction motors where the rated power matches the soft starter power.

Q:What protection features does the soft starter include?

It includes protection against voltage loss, undervoltage, overvoltage, over-current, overheating, phase losses, three-phase unbalance, and short circuits.

Q:What are the operating environmental conditions?

It operates at altitudes under 3000 meters, temperatures from -25 to +40 degrees Celsius, and humidity under 90% RH in non-condensing, non-flammable environments.

Q:Can the soft starter be customized for specific applications?

Yes, it offers optional functions like start delay, running delay, auto-restart settings, and 4-20mA analog output for real-time monitoring.
