EKC2SU Series ac contactors are used for controlling 3-phase motor circuits up to 690v Ac. These contactors are of the block type design with 3 main poles. Built in 1NO+1NC auxiliary contact and surge suppression, resulting in installation time and cost savings.
Compared with contactors using extremal surge suppressors, contactor products using built in surge suppressors will have more reliable performance and at the same time the surges are handled by the contactor itself and the surge never reaches the control circuit.
