Schneider Electric 40A 3-Pole Contactor

This Schneider Electric LC1D40AG7 is a TeSys Deca magnetic contactor built for motor control up to 40A at 440V AC-3 duty. It operates on a 120V 60Hz AC coil and fits a 55mm wide DIN-rail or screw mounting. The unit includes EverLink BTR power terminals, screw clamp control terminals and built-in 1NO+1NC mirror-certified auxiliary contacts. It suits industrial panels needing reliable switching up to 3600 cycles per hour in 60°C environments.

Suits 3-phase motor starters up to 30HP at 480V

This contactor serves builders wiring 3-phase motor starters rated 10HP at 200-208V, 10HP at 240V, 30HP at 480V and 30HP at 600V. It also fits panels requiring SCCR up to 100kA with 480V 110A breakers or 600V 90A Class J/CC fuses. It does not suit DC coil applications, single-phase loads needing different pole counts, or installations that cannot accommodate a 55mm wide DIN-rail device.

120V AC coil voltage

The defining specification is the 120V 60Hz AC control coil; the contactor will not operate on DC or other AC voltages without a different coil. All other ratings — 40A AC-3, 18.5kW at 400V, 30HP at 480V, 55mm width and 3600 cycles/hour — depend on this coil voltage being present in the control circuit.

Questions about this item

How do I verify the contactor is operating correctly after installation?

Confirm the coil energises at 120V 60Hz, the three main poles close to pass motor current, and the built-in 1NO+1NC auxiliary contacts change state — the NC contact is mirror certified for safety feedback.

What accessories are included and what must be purchased separately?

The contactor ships with the 120V AC coil and integrated 1NO+1NC auxiliary contacts; EverLink BTR power connectors and screw clamp control terminals are built in. Overload relays, mechanical interlocks or additional auxiliary blocks are sold separately.

Which coil voltage version should I select for a 120V control circuit?

Choose the LC1D40AG7 — it is supplied with a 120V 60Hz AC coil matched to your control voltage. Other coil voltages exist in the range but are different part numbers.
