Square D LC1D25BD – Frequently Asked Questions

1) What motor FLA ratings and coil voltages can I get on the Square D TeSys Deca LC1D contactor?
The TeSys Deca LC1D line runs from 9A up to 150A motor FLA, in 9, 12, 18, 25, 32, 38, 40, 65, 80, 115 and 150A sizes. Coils come as 24V DC, 120V AC and 240V AC, but not every coil pairs with every size. Confirmed combinations include LC1D09F7 (9A, 24V DC), LC1D12B7 (12A, 240V AC), LC1D12BD (12A, 24V DC), LC1D18U7 (18A, 240V AC), LC1D25U7 and LC1D25BD (25A), LC1D32U7 and LC1D32BD (32A), LC1D38F7 (38A, 240V AC), LC1D40AF7 (40A, 240V AC), LC1D40G7 and LC1D65G7 (120V AC), LC1D80G7/LC1D80BD, LC1D115G7/LC1D115BD and LC1D150G7/LC1D150BD. Order by the full part number so you get the right coil.
2) What horsepower will the 18A TeSys Deca contactor handle?
At 18A AC-3 the device carries up to 3hp at 230/240V AC 50/60Hz, 4kW at 220...230V AC and 7.5kW at 380...400V AC. The 18A rating applies at ambient under 60 degrees C up to 440V AC in AC-3. For larger motors step up the FLA code in the same family, which runs to 150A.
3) Is the TeSys Deca LC1D contactor UL Listed for use in a US control panel?
Yes. It is UL Listed to UL 60947-4-1 and CSA Certified to CSA C22.2 No 60947-4-1 and No 14, with rated insulation voltage of 600V per UL and CSA (690V per IEC 60947-4-1). It also carries CCC, CB Scheme, EAC, UKCA and marine certification, and conforms to IEC and EN 60947-4-1 and 60947-5-1. Overvoltage category III.
4) My existing contactor is worn out - should I buy a renewal kit or a complete TeSys Deca contactor?
That depends on what is in the panel now. Eaton offers renewal parts such as the Freedom Series A1 contactor kit and the Citation B1 three-pole contactor renewal kit, which rebuild an existing Eaton contactor rather than replace it, so the panel wiring and footprint stay as they are. A Square D TeSys Deca LC1D is a complete 3-pole contactor with its own coil and 1NO+1NC auxiliary contacts, which is the route when the existing device is a TeSys Deca, when the old frame is no longer serviceable, or when you are building a new motor starter assembly.
5) What is the closest cross-brand equivalent to a 9A TeSys Deca 3-pole IEC contactor?
For a small 3-pole IEC contactor in the same class as the Square D TeSys Deca LC1D09F7 (9A motor FLA), the ABB AF-09301013 from the AF series is a 3-pole contactor rated 9-16A AC-3 with a 1NO auxiliary contact. The TeSys Deca unit carries 1NO+1NC built-in auxiliary contacts rather than a single NO, so if your control scheme uses a normally closed interlock you need to account for that difference or add an auxiliary block. Both are 3-pole IEC-style contactors for motor switching.
6) Does the TeSys Deca contactor come with auxiliary contacts, or do I have to add a block?
The 18A TeSys Deca with the 240V AC coil ships with 1NO + 1NC auxiliary contacts built in, so you have a holding contact and an interlock without bolting on an add-on block. The power side is 3-pole, 3 NO.
7) Will a TeSys Deca contactor mount on DIN rail in my control panel, or does it need a back plate?
Both work. The TeSys Deca supports rail or plate mounting, so it drops onto DIN rail in a panel builder assembly or screws directly to a sub-panel. Front face ingress protection is IP20 per IEC 60529, which means it is an open-style device meant to live inside an enclosure, not on its own.
8) What wire size and torque do the power terminals on the TeSys Deca take?
The power circuit uses screw clamp terminals tightened to 1.7 N.m with a flat 6 mm driver. Size your lugs and ferrules to that terminal and torque the screws with a calibrated driver, since under-torqued IEC power terminals are the usual cause of heating at the contactor.
9) Is this a reversing contactor, and can I use it for a reversing starter?
No. The TeSys Deca LC1D described here is nonreversing, open style, 3-pole with 3 NO contacts. To reverse a motor you need two of them mechanically and electrically interlocked, or a factory reversing assembly.
10) What else does ZenSupply carry if I need an IEC contactor in the 9 to 16A range instead of Square D?
The ABB AF16 is the closest cross-brand option we hold: the ABB AF-09301013 is a 3-pole AF Series contactor rated 9-16A AC-3 with one NO auxiliary contact. Eaton's AE16 Series three-phase IEC contactor/starter is another route for small motor control. Both differ from the Square D LC1D in auxiliary contact arrangement, so check your control scheme: the 18A TeSys Deca with the 240V AC coil includes 1NO+1NC, while the ABB unit lists a single NO auxiliary.
11) Should I pick the 24V DC coil or the 240V AC coil on a TeSys Deca?
Pick by what your control circuit runs on. A 24V DC coil (the BD and the 9A F7-coded DC unit) suits PLC-driven panels where outputs switch 24V DC and you want low control voltage in the door. The 120V AC and 240V AC coils suit a hardwired control transformer scheme with pilot devices on line voltage. Sizes available on 24V DC include 9, 12, 25, 32, 80, 115 and 150A; 240V AC covers 12, 18, 25, 32, 38, 40, 80, 115 and 150A; 120V AC covers 40 and 65A.
12) Is the Eaton AE16 contactor a direct replacement for a TeSys Deca LC1D contactor?
The Eaton AE16 Series is a three-phase IEC contactor/starter for motor control, so it addresses the same application as the Square D TeSys Deca LC1D line, but it is not a drop-in swap. The two lines use different frame footprints, terminal layouts and coil part numbers, so a panel already drilled and wired for an LC1D frame will need the mounting and wiring confirmed against the AE16 dimensions before you substitute. Match the coil voltage you are replacing as well - the TeSys Deca contactors are offered with 24V DC, 120V AC and 240V AC coils.
13) I only need to replace the coil on a 240V contactor - is a TeSys Deca the right purchase?
No. If the contacts are sound and only the coil has failed on an existing Eaton Freedom device, the Eaton Freedom coil and contactor kit for 220-240V, 65mm AC frames is the component-level part for that job. A Square D TeSys Deca LC1D is a complete contactor assembly with the coil built in and is not sold as a loose coil, so buying one to harvest a coil leaves you with a mismatched part. Order the TeSys Deca when you are replacing or specifying the whole contactor - it is available with 240V AC coils across the 12A through 150A motor FLA range.
14) What should I use instead if the motor draws more than 16A?
The ABB AF-09301013 covers a 9-16A AC-3 band, so a larger motor needs a bigger frame. The Square D TeSys Deca LC1D line continues well past that point, with motor FLA ratings of 18A, 25A, 32A, 38A, 40A, 65A, 80A, 115A and 150A, so you can stay in one IEC contactor family as the horsepower climbs and keep coil voltage and panel conventions consistent across a multi-motor control enclosure.
15) Can I use this contactor on a DC circuit?
The power circuit is rated up to 690V AC at 25...400Hz, or up to 300V DC, so DC switching is within the rated operational voltage. Note the AC-3 current and kW figures quoted for the device are motor ratings on AC; DC load breaking on a 3-pole IEC contactor usually requires poles in series, so size the application to the DC voltage rating rather than the AC-3 motor rating.
16) Can I use a TeSys Deca contactor to switch resistive loads like heaters, not just motors?
Yes, resistive load switching is one of the listed applications alongside motor starter assemblies and OEM control panels. For resistive duty, size against the AC-1 style continuous current rather than the AC-3 motor figures quoted for the unit, since the 18A AC-3 number is a motor rating at up to 440V AC.
