1. QNZ1-Q Series Energy-Saving DC Contactors

   Models: QNZ1-50Q/100Q/200Q/300Q/400Q/500Q/600Q/800Q/1000Q/1200Q/1650Q/2000Q/3500Q/5050Q  

   Features: Protection rating up to IP67, waterproof and dustproof, excellent vibration resistance, suitable for extreme cold and high-temperature environments, energy-saving coil that does not heat up. This series is the preferred product for engineering machinery.

2. QNZ1-QW Series Products

   Models: QNZ1-50QW/100QW/200QW/300QW/400QW  

   Features: The QW series is derived from the Q series. It offers a protection rating up to IP67, waterproof and dustproof, excellent vibration resistance, suitability for extreme cold and high-temperature environments, and an energy-saving coil that does not heat up.

3. QNC-WH Arc-Free Energy-Saving Three-Phase AC Contactors 

   Models: QNC11533WH/15033WH/18533WH/20033WH/22533WH/26533WH/33033WH/40033WH/50033WH/63033WH/80033WH/100033WH/125033WH/165033WH/200033WH/350033WH/505033WH  

   Features: Intelligent products with voltage sag resistance, arc-free breaking, energy-saving coil (coil does not heat up), and communication interface capability. They meet the requirements for high-current three-phase AC contactors used in engineering machinery. Among them, the QNC-5050 model has a rated current of 5050A, making it one of the highest-current AC contactors in the global market.

4. QNJY Series Silent Contactors

   Models: QNJY-1522/1822/2522/3222/4022/5022/6522/7522  

   Features: Compatible with AC or DC control; when DC-controlled, no AC hum, low noise. The electromagnetic system features a magnetic latching design, and the coil control is energy-saving, managed by a circuit board. After the contactor closes, the coil maintenance power consumption is ≤3W. Additionally, the QNC1-9511J miniature contactor is suitable for low-current three-phase AC contactors used in engineering machinery.
