Intelligent Power Distribution Drawer-Type Panel Switchgear

The Intelligent Power Distribution Drawer-Type Panel Switchgear from Lugao Power Co., Ltd. is a high-performance low-voltage assembly that combines intelligent protection, metering, and communication. Unlike traditional fixed panels, this drawer-type version allows each circuit unit to be inserted or withdrawn without shutting down the entire system. Each drawer houses a dedicated circuit breaker, controller, and sensors. The "intelligent" capability comes from built-in power quality analyzers, Modbus TCP/IP or Profibus communication, and automatic failure alerts. The Switchgear is suitable for AC 690V, 50/60Hz systems, rated current up to 6300A. It meets IEC 61439-1/2 and GB/T 7251 standards.

Product Features and Application (With Q&A Format)

This section addresses common buyer concerns and highlights the engineering advantages of the Intelligent Power Distribution Drawer-Type Panel Switchgear.

Q1: How does the drawer mechanism improve maintenance?

A: The unit features a three-position drawer (connected/test/disconnected) with mechanical interlocks. You can replace a faulty drawer in under 60 seconds without turning off adjacent circuits. This is a key benefit of the Intelligent Power Distribution Drawer-Type Panel Switchgear for critical facilities.

Q2: What"intelligent" functions are built-in?

A: Real-time voltage, current, power factor, and harmonics monitoring. Automatic alarm on overload, short circuit, or temperature rise. Data logs can be exported via RS485 or Ethernet. Remote trip/close control from a central SCADA system.

Q3: Is the drawer mechanism reliable after many insertions?

A: Yes. Each drawer is tested for 5,000 mechanical operations and 1,000 electrical operations without performance degradation. The contacts are silver-plated with spring-loaded pressure.

Q4: Where can this product be installed?

Application List:

1. Data Centers: For redundant power paths and minimal MTTR (Mean Time To Repair).

2. Hospitals: Critical life-support circuits require uninterrupted power.

3. Industrial Plants: Motor control centers (MCC) for conveyors, pumps, and compressors.

4. Commercial Complexes: Mall lighting and HVAC distribution.

5. Renewable Energy: Solar/wind integration with smart grid feedback.

● Port: Shanghai / Ningbo.

● Shipping: Sea freight (FCL or LCL), air freight for urgent spare drawers.

Frequently Asked Questions

Q1: Can I purchase a single drawer as a spare part without buying the whole panel?

A: Yes. Lugao Power Co., Ltd. sells individual intelligent drawers. We can manufacture a matching spare drawer according to the original drawing, drawer label, circuit configuration and component model. Final compatibility should be confirmed during the technical review stage.

Q2: Does the Intelligent Power Distribution Drawer-Type Panel Switchgear support remote reset after a fault?

A: Yes, via the communication module. The operator can remotely disconnect, diagnose the fault, and reconnect (if allowed by local safety codes). However, manual inspection is still recommended for short-circuit trips.

Q3: What is the maximum number of drawers per panel for your product?

A: For 160A drawers, we can install up to 24 units in a 2200mm high panel. For 630A drawers, maximum 12 units. The layout follows Form 4b separation, meaning each drawer is fully isolated in its own metal compartment.

Q4: Do you provide installation and commissioning service?

A: We provide remote video commissioning as standard. Optional: On-site commissioning by Lugao engineers (travel expenses + daily rate, 1-year warranty extension included).*

Q5: Can you integrate third-party breakers like Mitsubishi or LS?

A: Absolutely. The drawer chassis is designed to accept most major brands: ABB Tmax/Sace, Schneider NSX/MTZ, Siemens 3VA/3WL, CHINT, and others. Just specify the breaker model when you purchase.

After-Sales Service & Warranty

Warranty Period: 12 months (1 year) from the date of shipment.
