Description

TeSys K contactor, 3 poles (3NO), for motor control applications up to 9A/690V AC-3 (4kW@400V), and for non-inductive load control applications up to 20A/690V AC-1. It provides a 24V 50/60Hz AC coil, 1NC 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).
