3. Core Product Advantages
- High-Current Silver Alloy Contact System
Silver-cadmium alloy composite contacts feature ultra-low contact resistance, strong arc ablation resistance, and extend electrical service life under long-term heavy frequent switching loads.
- Sealed Efficient Arc Extinguishing Chamber
Independent arc extinguishing structure rapidly absorbs and quenches electric arcs during circuit breaking, avoids short-circuit risks, and greatly improves operation safety for high-current working conditions.
- Anti-Vibration Stable Electromagnetic Coil
Universal 50/60Hz AC coil with low power consumption, stable pull-in and release performance. Anti-shock design adapts to vibration-intensive factory and construction site environments.
- Flame Retardant Industrial Housing
High-temperature resistant PA66 flame retardant plastic shell, anti-aging, dust-proof and moisture-proof, suitable for indoor power distribution rooms and harsh workshop production lines.
- Full Range Size Uniform Modular Design
Consistent wiring layout and installation size across all 115A~800A models, easy for unified cabinet design and spare parts replacement. Auxiliary contacts can be freely assembled for interlock and signal feedback.
- Global Export Qualified Certification
CE certified, fully meets EU electrical safety standards, supports direct export to Europe, Southeast Asia, Middle East, Africa and Latin America markets.
4. Main Application Industries & Scenarios
- Heavy-duty 3-phase asynchronous motor start-stop control
- Central air conditioning, refrigeration compressors, cooling tower fan control
- Large water pump, oil pump, industrial fan power switching
- Complete low-voltage distribution cabinets, PLC automation control systems
- CNC heavy machine tools, packaging production lines, lifting construction machinery
- Power distribution equipment for mining, chemical and textile factories
5. Standard Installation & Wiring Guide
- Vertical mounting: Fix the contactor to cabinet mounting plate via bottom screw holes to guarantee stable electromagnetic attraction.
- Main circuit wiring: 3-phase power input connects to L1, L2, L3 terminals; motor/load output connects to T1, T2, T3 terminals.
- Control circuit wiring: Connect control power to coil A1/A2 terminals strictly according to ordered coil voltage; mismatched voltage will burn the coil.
- Matching protection: Match thermal overload relay of corresponding current grade below the contactor to realize motor overload and phase loss protection.
- Auxiliary contacts: Install side-mounted auxiliary modules for interlock, indicator light and signal feedback functions.
