  • Secure screw-clamp terminals give vibration-resistant wiring connections
  • Versatile DIN rail or plate mounting suits diverse enclosure layouts

Industrial Motor Control

This Schneider Electric TeSys Deca contactor switches three-phase loads up to 40 A at 690 V AC. A 120 V AC coil drives four power poles plus two built-in auxiliary contacts rated 1NO/1NC. Screw-clamp terminals accept solid or stranded conductors for secure wiring in panels or machine builders' cabinets. The compact 3.58 in by 1.77 in body mounts on DIN rail or directly on a plate.

Panel Builders and OEMs

It suits engineers who need a non-reversing IEC contactor with a transparent cover for visual inspection. Installers who require a factory-fitted mechanical interlock, a reversing pair or an integrated overload relay should select a different TeSys variant. Applications demanding DC coil operation or spring-cage terminals are not addressed by this model.

120 V AC Coil Voltage

The coil must be energised from a 120 V AC control circuit; any other voltage will not operate the contactor reliably. Verify that the control supply matches this value before specifying the part.

Questions about this item

What auxiliary contacts must the panel already provide for the 1NO/1NC block on this contactor?

The contactor includes a built-in 1NO/1NC auxiliary block, so no separate auxiliary contacts are required for basic control circuits.

Will the 120 V AC coil operate correctly on the same DIN rail as older TeSys Deca units?

Yes, the coil is rated for 120 V AC and the unit mounts on standard DIN rail, so it can sit beside existing TeSys Deca contactors on the same rail.

How can I confirm the 40 A inductive load is switching cleanly after wiring?

Measure the voltage drop across each of the four main poles under load; a low, balanced reading on all poles shows the contactor is operating as intended.
