Description
TeSys D contactor, 3 poles (3NO), for motor control applications up to 18A/690V AC-3/3e (7.5kW@400V). It provides a 240V 50/60Hz AC coil, 1NO+1NC built-in auxiliary contacts (NC mirror certified), connection by screw clamp terminals. For operating rates until 3600 cycles/hour and environments until 60°C, it procures high reliability and durability. Compact (45mm width), DIN-rail mounting or screw fixing. Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh).
Features
- Rated for 18 Amps under inductive (AC-3) loads up to 440V, this 3-pole contactor is engineered to control standard three-phase electric motors up to 7.5 kW (10 hp). It easily manages heavy mechanical startup currents for conveyor belts, commercial ventilation systems, and industrial pumps, preventing contact welding and premature component failure.
- Equipped with an optimized 240V AC coil (under code U7), this contactor drops directly into standard North American commercial power configurations without requiring a control transformer. The dual-frequency 50/60Hz coil architecture accommodates subtle power grid fluctuations, preventing coil chatter and ensuring reliable, snappy contact engagement.
- Featuring factory-integrated, highly reliable 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contacts, this unit allows for simultaneous control logic configuration. This enables commercial panel builders to establish low-voltage status feedback to a PLC, trigger remote dashboard pilot lights, or wire up essential hardwired electrical safety interlocks without purchasing add-on auxiliary blocks.
- Built within the standardized TeSys Deca space-saving footprint, this device features a dual-mounting chassis that snaps directly onto standard 35mm DIN rails or mounts securely to a sub-panel backplate. This allows plant electricians to rapidly retrofit legacy hardware or build high-density control panels without wasting valuable enclosure space.
