Our products combine durability, safety, and energy efficiency for consistent performance in demanding environments.
With over a decade of experience, we focus on innovation and sustainability, delivering professional-grade solutions that support global industries and energy-efficient systems.
We offer a complete range of contactors and relays engineered for precision and reliability. Our portfolio includes AC Contactors, DC Contactors, Thermal Overload Relays, and Smart Relays. Each product ensures stable contact performance, excellent arc suppression, and long mechanical life for dependable operation in automation and power control systems.
All products comply with international safety standards and are widely used in motor control panels, distribution boards, and automation lines where reliability is essential.
Our AC Contactors are designed for alternating current circuits, providing efficient switching for motors, lighting, and HVAC systems. Meanwhile, DC Contactors are optimized for direct current applications such as battery systems and renewable energy installations. Both types feature robust designs and CE certification for reliable performance in industrial and commercial environments.
| Type | Application | Key Benefit |
|---|---|---|
| AC Contactor | Motor control, HVAC, lighting | High endurance and arc suppression |
| DC Contactor | Battery systems, solar control | Stable performance under DC load |
Thermal Overload Relays protect motors from overheating and overcurrent, automatically disconnecting circuits to prevent damage. For advanced automation, our Smart Relays integrate digital control and monitoring features, enabling flexible programming and real-time management. Both demonstrate our R&D strength and commitment to innovation in industrial automation.
Our contactors and relays are used in industrial control, motor protection, and automation systems. They play key roles in:
Motor starting and stopping in production lines
Lighting and HVAC control in commercial facilities
Power switching in renewable and backup energy systems
Automation panels in manufacturing and assembly plants
Built for endurance and reliability, these components deliver stable performance even under harsh conditions.
