TeSys K reversing contactor, 3 poles (3NO), for motor control applications up to 12A/690V AC-3 (5.5kW@400V). It provides low consumption 24V DC coils with transient suppressor module, 2NC built-in auxiliary contacts, connection by screw clamp terminals. For operating rates until 600 cycles/hour in AC-3 and environments until 50°C, it procures reliability and durability to standard applications. Compact (90mm width), DIN-rail mounting or screw fixing. With pre-wired reversing power connections, mechanical interlock (without electrical interlocking). Multi standards certified (IEC, UL, CSA, CCC, EAC).
