TeSys SK mini-contactor, 2 poles (2NO), for non inductive load applications up to 12A/690V AC-1, and for 1-phase motor control applications up to 6A/690V AC-3 (for 3-phase motors an add-on contact block LA1SK must be mounted on contactor). It provides a 48V DC control circuit with no inrush consumption, connection by screw clamp terminals. For operating rates until 1200 cycles/hour and ambient temperature -20/+50°C, it procures high reliability and durability. Compact (27mm width), for clipping on a 35mm DIN rail. Add-on contact blocks LA1SK (power pole, instantaneous auxiliary contacts) and suppressor modules LA4SK available (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC).
