Square D LC1D-G7 TeSys Deca IEC Contactor, 4-Pole, 2NO+2NC, 120VAC Coil

The Square D LC1D-G7 TeSys Deca IEC contactor is a 4-pole (2NO+2NC) device engineered for non-inductive, Class A resistive load applications, making it suitable for motor starter and control panel builds across almost any application. This contactor is offered with a Motor FLA rating spanning 25A to 40A, letting panel builders select the load capacity that fits their design while sharing the same 120V AC 50/60Hz coil, 1NO+1NC built-in auxiliary contacts, and open-style (no enclosure) IP20 front-face construction across the range.

Square D LC1D128G7 – Frequently Asked Questions

1) What coil voltage does the LC1D-G7 contactor use, and will it work on a 120V control circuit?
The G7 suffix on the TeSys Deca means a 120V AC 50/60Hz coil, so it drops straight onto a standard 120V control transformer secondary or a 120V control circuit. Both current ratings share the same coil, so a 25A and a 40A unit can be driven from the same control scheme in a panel.
2) Which Square D LC1D part number do I order for 25A versus 40A?
Two current ratings are offered on the LC1D-G7 TeSys Deca: LC1D128G7 for 25A Motor FLA and LC1D258G7 for 40A. Everything else stays the same between them, including the 120V AC coil and the 1NO+1NC built-in auxiliary contacts.
3) Is the Square D LC1D-G7 contactor UL listed for a panel I have to get inspected?
Yes. The LC1D-G7 is UL Listed and CSA Certified, built to IEC 60947-4-1 and IEC 60947-5-1 with UL 60947-4-1 and CSA C22.2 No 60947-4-1. The power circuit carries a 600V UL/CSA rating with Ui 690V insulation to IEC 60947-4-1 and a 6kV Uimp impulse withstand. It also carries CB Scheme, CCC, EAC, UKCA and marine certification.
4) What is the closest IEC contactor to the Square D LC1D-G7 if I need a three-pole device instead of four-pole?
The Square D LC1D-G7 TeSys Deca is a 4-pole contactor with a 2NO+2NC pole arrangement, so all four poles switch together and two of them sit normally closed. For a three-pole arrangement, the ABB AF-09301013 is an AF16 three-pole contactor with one NO auxiliary contact and a 9 to 16A AC-3 rating, and the Eaton AE16 is a three-phase IEC contactor/starter for motor control. Both of those switch three phases, which is the usual choice for a standard three-phase motor feed, while the LC1D-G7 arrangement is aimed at non-inductive resistive Class A load switching with normally closed poles in the same frame.
5) Can I use an Eaton Freedom or Citation contactor kit in place of a Square D LC1D-G7?
No. The Eaton 6-44-2 is a Freedom Series A1 contactor kit sold as a motor control renewal part, the Eaton 6364 is a Citation B1 three-pole contactor renewal kit, and the Eaton 932563 is a Freedom coil and contactor kit for 220-240V AC in a 65mm size. Those are replacement parts for existing Eaton starters, so they go into the Eaton frame they were built for. The Square D LC1D-G7 TeSys Deca is a complete open-style contactor with a 120V AC coil and built-in 1NO+1NC auxiliary contacts that mounts on DIN rail or a panel plate, so it is what you order when you are building or replacing the whole device rather than rebuilding an Eaton one.
6) My coil control voltage is 230V, not 120V. What should I use instead of the LC1D-G7?
The Square D LC1D-G7 TeSys Deca is built around a 120V AC 50/60Hz control coil, so a 230V control circuit will not pick it up. The Eaton 932563 Freedom coil and contactor kit is specified for 220-240V AC in a 65mm size and is the comparable that matches that control voltage band. Confirm the frame size against the starter you are feeding, since that Eaton kit is dimensioned for a 65mm body.
7) Do I need to add an auxiliary contact block to the LC1D-G7 for interlocking or run signalling?
Not for a single run signal or a basic interlock. The contactor ships with 1NO plus 1NC built-in auxiliary contacts, which covers a seal-in circuit plus one status or interlock contact. Anything beyond that pair means adding an auxiliary block.
8) Can the LC1D-G7 contactor be DIN rail mounted, or does it need a back plate?
Either one. The TeSys Deca LC1D-G7 supports rail or plate mounting, so it works on a DIN rail in a standard panel or screwed directly to a subpanel where rail space is tight. It is an open style device with IP20 protection on the front face per IEC 60529, so it has to go inside an enclosure.
9) What is the maximum operating voltage of the LC1D-G7 power circuit?
Rated operational voltage Ue on the power circuit is up to 690V AC at 25 to 400Hz, and up to 300V DC. The AC-1 current rating, however, is stated at up to 440V AC with Ie at under 60 degrees C, so size the load current against that figure rather than the 690V ceiling.
10) Which contactor gives me more built-in auxiliary contacts for interlocks, the Square D LC1D-G7 or the ABB AF16?
The Square D LC1D-G7 TeSys Deca includes 1NO+1NC built-in auxiliary contacts for signalling and control circuit integration, so you get both a normally open and a normally closed auxiliary without adding a block. The ABB AF-09301013 AF16 is listed with one NO auxiliary contact. If your interlock scheme needs a normally closed auxiliary as supplied, that is the difference to weigh between the two.
11) I need a contactor and overload starter combination. Does the Square D LC1D-G7 cover that or do I need something else?
The Square D LC1D-G7 TeSys Deca is a contactor on its own, an open-style IP20 front-face device for rail or plate mounting in motor starter assemblies and control panel builds, so overload protection is added separately in the panel. The Eaton AE16 is described as a three-phase IEC contactor/starter for motor control, so it is the comparable to look at when you want the starter function in the ordered item rather than assembled around it.
12) Are Square D TeSys Deca contactors RoHS and heavy-metal free for a green building spec?
The TeSys Deca LC1D-G7 is a Green Premium product: toxic heavy metal free, mercury free, in RoHS EU scope, and packed in recycled cardboard under Square D's sustainable packaging program. That covers most of what a LEED or institutional procurement submittal asks for on a control component.
13) What wiring terminal size does the LC1D-G7 contactor take?
Contact compatibility on the LC1D-G7 is M6, so lug and conductor terminations should be matched to M6 hardware when you build the power connections.
