TeSys K contactor, 4 poles (2NO+2NC), for non-inductive load control applications up to 20A/690V AC-1. It provides a 120V 50/60Hz AC coil, without built-in auxiliary contact, connection by screw clamp terminals. For operating rates until 600 cycles/hour and environments until 50°C, it procures reliability and durability to standard applications. Very compact (45mm width), DIN-rail mounting or screw fixing. Multi standards certified (IEC, UL, CSA, CCC, EAC), Green Premium compliant (RoHS/REACh).
