TeSys Deca reversing contactor, 3 poles (3NO), for motor control applications up to 38A/440V AC-3/3e (18.5kW@400V). It provides 24V DC coils with transient suppressor module, 2NO+2NC built-in auxiliary contacts (NC mirror contacts), connection by screw clamp terminals. For operating rates until 3600 cycles/hour and environments until 60°C, it procures high reliability and durability. 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, Marine).
