Low noise: the contactor eliminated the low-frequency buzzing sound in the contactor work, creating a super-quiet environment. Energy saving: optimized electromagnetic system, greatly reduced contactor holding power, energy-efficient. Compact size, more user-saving installation space, easy to install and maintain. Smooth operation, superior performance. Rated Working System a) Eight-Hour Working System This working system is the basic working system, and the agreed free air heating current Ith of the contactor is determined by this working system. b) Intermittent Working System The rated operating frequency of the contactor under this working system is 30 times/h, and the load factor is 40%. Operation Conditions When the ambient air temperature is in the range of -5C-+60, when the contactor attracting coil is applied with the rated control power voltage Us to make it heat to a stable state, the contactor should be within the range of (85%-10%) Us It can be closed reliably under any voltage; its release voltage is (20%-75%) Us.
