AI-Powered supplier vetting
SummaryYueqing Aukeman Trading Co., Ltd. is identified as a China-based limited trading company, with the entity type also listing manufacturer/factory and other. Its stated product focus includes electronic, voltage, current, and time relays and motor protectors. The supplier reports ISO 9000 and ISO 9001 certifications, OEM/ODM services, three experienced R&D engineers, two production lines, and 6–10 quality-control staff. It reports export activity since 2010, self-operated import/export rights, 90% export sales, and order fulfillment within 15 working days in both peak and off-peak periods. However, evidence is inconsistent: one slice describes a separate online-notepad business, while another indicates only one recorded trade transaction after registration in May 2025. No explicit after-sales policy, financial statements, or verified customer case details are provided.
Supplier typeThe supplier is explicitly described as a trading company, while its entity classification also includes manufacturer/factory and other. Its stated operations include exporting relay and motor-protection products and providing sourcing-agent services, indicating a trading-led business with claimed manufacturing or production linkage.
CertificationsThe supplier reports holding ISO 9000 and ISO 9001 management-system certifications. The slices do not provide certificate numbers, issuing bodies, scope, or validity dates, but the stated certifications are explicit evidence of certification holding.
R&D capabilityThe supplier reports three R&D engineers from China Chint Group with 25 years of industry experience, a technology research and development base, and multiple design patents. This is explicit evidence of product-development capability, although another slice reports total R&D engineer experience as under five years, creating an unresolved inconsistency in the profile.
Production capacityThe supplier claims production and export of voltage relays, time relays, and motor protectors, with two production lines, 6–10 quality-control staff, and lead times within 15 working days in both peak and off-peak seasons. However, the stated annual output is not independently corroborated and the profile contains conflicting business descriptions, so the evidence supports capability but should be verified.
Customization capabilityThe supplier explicitly states that it provides OEM and ODM services for voltage relays, time relays, and motor protectors. This directly supports customization capability, although no details on minimum order quantities, engineering process, tooling, or customization scope are provided.

A:
The protector provides overload, phase failure, rotor-locked, and asymmetry protection for three-phase motors.
Q:How is the setting current adjusted?
A:
The setting current can be adjusted by potentiometer or through the toggle switch keys on the protector panel.
Q:What happens if the set current is out of range?
