Deqing Leixin Coating Equipment Co., Ltd., established in 2011, is a professional manufacturer specializing in electrical control cabinets with advanced protection functions. Our Electrical Control Cabinet with Overload, Short Circuit, Phase Loss, and Leakage Automatic Cut-off Protection is designed to safeguard critical industrial equipment and personnel. With ISO9001 certification and over a decade of manufacturing experience, we deliver reliable, high-performance solutions that meet international standards. This cabinet integrates multiple protection mechanisms into a single compact unit, ensuring uninterrupted operation and minimizing downtime.
The cabinet features a robust cold-rolled steel enclosure (1.5-2.0mm thickness) with IP54 protection as standard, and IP65 is available for harsh environments. It is equipped with high-quality circuit breakers, contactors, thermal relays, and phase-loss protection modules that automatically trip the circuit when any abnormality is detected. Key functions include:
- Overload Protection: Prevents damage from prolonged current exceeding rated capacity.
- Short Circuit Protection: Instantaneous cut-off during high fault current events.
- Phase Loss Protection: Detects missing phase and disconnects power to avoid motor burnout.
- Leakage Protection: Residual current detection (30mA/100mA/300mA optional) ensures personnel safety.
- Automatic Cut-off: All faults trigger automatic disconnection with visual alarm indication.
Technical specifications are summarized below:
| Parameter | Value |
| Rated Voltage | 380V / 440V AC (3-phase, 50/60Hz) |
| Rated Current | Up to 630A (customizable) |
| Short Circuit Capacity | 50kA / 65kA |
| Leakage Sensitivity | 30mA / 100mA / 300mA (selectable) |
| Response Time | <0.1 second (short circuit/leakage) |
| Operating Temperature | -20°C to +55°C |
| Enclosure Protection | IP54 (IP65 optional) |
| Certification | ISO9001 |
Key advantages of choosing our control cabinet:
- Integrated multi-protection: One cabinet covers overload, short circuit, phase loss, and leakage, reducing wiring complexity.
- High-quality components: We use reputable brands (Schneider, Siemens, or equivalent) for breakers and relays, ensuring long service life.
- Customizable design: Size, layout, terminals, and additional features (e.g., surge protection, remote monitoring) can be tailored to your needs.
- Easy maintenance: Clear labeling, modular structure, and accessible wiring terminals simplify troubleshooting.
- Compliance: Manufactured under ISO9001 quality management system, meeting international electrical safety standards.
Our control cabinets are widely used in manufacturing lines, pumping stations, HVAC systems, conveyor systems, and other industrial applications where reliable power distribution and personnel safety are critical. They are suitable for both indoor and outdoor installations with appropriate enclosure options.

Frequently Asked Questions (FAQ)
Q1: Does this control cabinet provide all four protections simultaneously?
A: Yes, it integrates overload, short circuit, phase loss, and leakage protection in one unit. Each function can be independently adjusted or enabled.
Q2: What is the typical response time for short circuit and leakage protection?
A: The response time is less than 0.1 second for short circuit and leakage events, ensuring rapid disconnection to prevent damage.
Q3: Can the cabinet be customized for different voltage levels (e.g., 220V, 690V)?
A: Yes, we can design the cabinet for any voltage from 220V to 690V AC, and also for DC systems. Please specify your requirements.
Q4: What is the enclosure protection grade? Can it be used outdoors?
A: Standard is IP54 (splash-proof). IP65 (dust-tight and water-jet resistant) is available for outdoor or dusty environments.
Q5: Do you have certifications other than ISO9001?
A: Our products are manufactured under ISO9001 quality management system. Specific certifications like CE, UL can be requested for large orders, subject to assessment.
Q6: What is the lead time for a standard cabinet?
A: Standard models typically ship within 15-20 working days. Customized orders may take 25-35 days, depending on complexity.
Q7: How do I choose the correct leakage sensitivity for my application?
A: 30mA is recommended for personnel protection, 100mA for general equipment, and 300mA for fire prevention. Our technical team can advise based on your environment.
Q8: What warranty do you offer on the control cabinet?
A: We provide a 12-month warranty from the date of shipment, covering manufacturing defects. Extended warranty is available upon request.
