Low power consumption:
The CH series modular contactor optimizes the electromagnetic system, greatly reducing the holding power of the contactor, and completely solves the problem of high energy consumption of traditional contactors.
Low noise:
CH series modular contactor adopts a new design to improve product reliability.60% of the production process is automated, and key processes throughout the process are monitored automatically. Eliminate the noise problems encountered in the operation of traditional contactors from the design and manufacturing process.
Super long life:
Electrical life greater than 100,000 times
Mechanical life is more than 12,000,000 times
