AI-Powered supplier vetting

SummaryThe supplier operates across pneumatic machinery, electrical and mechanical equipment, instruments, hardware, plastic products, and related manufacturing and sales activities. It reports CE and RoHS certifications and has conducted regular fire drills, but no factory environmental impact assessment report is available. Manufacturing resources include three production lines, while ongoing batch quantity reconciliation is not performed. R&D personnel support product development and production, but no auditable design documentation was available; three R&D patents are reported. The supplier has participated in an offline trade show and accepts FOB, CIF, CFR, and EXW terms, but reports zero countries served overseas. It does not provide OEM services for well-known brands and has no available SDK. Financial credibility cannot be positively established from the provided records because the reported financial figures are zero.

Supplier typeThe supplier is a manufacturer and seller covering pneumatic machinery and components, electrical instruments, power electronic components, hardware, plastic products, mechanical equipment, and related products. Its stated product keywords include overvoltage protectors, electricity meters, intelligent protectors, and guide-rail Tuya intelligent protectors, indicating a diversified industrial and electrical equipment supplier profile.

CertificationsCE and RoHS certifications are explicitly reported, providing evidence of certification coverage for the supplier's products. However, the supplier reports no factory environmental impact assessment report, so the certification evidence does not establish full environmental compliance at the facility level.

Financial creditThe provided financial records report zero operating revenue, operating cost, gross profit, operating profit, gross margin, and current ratio for the stated periods. These records do not provide positive evidence of operating financial strength or financial credibility.

Production capacityThe supplier reports manufacturing activities for pneumatic machinery, electrical instruments, architectural metal and plumbing components, plastic products, and hardware, supported by three production lines. However, it does not conduct continuous quantity reconciliation for every batch or mass-production run, indicating a stated production-control deficiency.

Product Q&A

Q:What is the LYCB/3PN-DJ-H Smart Three-Phase Energy Meter Protector, and what are its core protection functions?

This is an 80A smart protection device designed for three-phase power systems. It integrates comprehensive power monitoring and safety protection features, including: Over-voltage and under-voltage protection Over-current and under-current protection Delay protection and timer switch functionality Bidirectional energy monitoring Phase loss (shortage phase), phase sequence, and voltage/current imbalance protection High temperature and current leakage protection

Q:How does the device protect and handle the three current lines (three-phase power) independently?

Current Imbalance Protection Phase Loss & Sequence Protection Note: Advanced three-phase metrics like current/voltage imbalance, phase loss, and phase sequence must be configured via the Tuya app.

Q:Which protection functions can only be configured via the mobile app?

To keep the physical device interface clean and user-friendly, certain advanced environment and phase-specific settings are restricted to app-only configuration: Voltage Imbalance Protection Current Imbalance Protection Shortage Phase (Phase Loss) Protection Phase Sequence Protection High Temperature Protection

Q:What do the different WiFi indicator light statuses mean, and how do I pair it to the app?

The WiFi indicator light has three distinct statuses: Fast Flashing: The device is actively searching for a WiFi signal and is ready for pairing. Slow Flashing: The device is currently offline or disconnected from WiFi. Solid/Long Light: The device is successfully connected to WiFi.

Q:Why does the user manual state that this device "cannot replace a normal circuit breaker"?

No Isolation Function: This product lacks a physical air-gap isolation mechanism. Before performing any line repairs or maintenance, you must disconnect the upstream circuit breaker. Direct Neutral (N) Line: The Neutral line of this product is directly connected through the device and does not feature a disconnection function. No Short-Circuit Interrupt Capacity: For dead short-circuits that create sudden massive surges, an external circuit breaker (such as a DZ47 or C65) must be installed ups
