Super long life, the contactor can withstands 100,000 full-load on and off under the AC-7a load category.
Super silent, it eliminates the obvious impact sound of the traditional contactor at the moment of pull-in and the low-frequency hum during the operation of the contactor.
Super energy-saving, in the working state, the contactor needs to maintain a long time of energization to keep the coil closed, and a large amount of electric energy is consumed in this process. This contactor greatly reducing the keeping power of the contactor with the optimized electromagnetic system.
Adopt superior insulation material to enhance the operation security to a great extent.
Compact modularization design, DIN rail mount.

1) 8-hour duty
This is the basic duty, and conventional heating current Ith of the contactor is determined by this working system.
2) Intermittent periodic duty
The rated operating frequency of the contactor under this duty is 30 times/h, and the load factor is 40%.
When the ambient temperature is in the range of -5°C to +60°C, apply the rated control power supply voltage Us to the contactor sucking coil to make it heat up to a steady state, and the contactor should be reliably closed under any voltage of (85% ~ 110%) Us. Its release voltage is (20%~75%) Us.
