Certification Description:YLK40 Series Alternating ContactorYLK40 series products are a new type alternative contactor (contactor in brief hereinafter), which was trial-manufactured and carried out recently by our company. It can be used for the circuit switching-on and switching-off in the electric system of alternating frequency 50Hz, setting voltage of main contact terminal up to 660V and working current up to 500A and it can become the motor starter, combining with the proper overheat relay or electronic protection device to protect the over load circuit in the operation.Because they adopted the new type system of arc extinguishing cover and connection terminal, YLK40 series products own the advantages of lower volume, higher ability of switching-on and switching-off, shorter safety area (arcing-over distance) and so on over the other domestic series contactors and become the ideal products chosen in the electric system.
