Square D LC1D12BL – Frequently Asked Questions

1) Will a Square D TeSys Deca LC1D contactor work with a 24V DC control circuit from my PLC?
Yes. The TeSys Deca LC1D contactors here are built with a 24V DC coil, and it is a low-consumption coil with a transient suppressor module included, so it can be driven directly from DC control wiring without adding a separate suppressor across the coil. If your control circuit is 120V AC or another voltage, this is the wrong coil code and you need a different LC1D variant.
2) Which Square D LC1D contactor do I need for a 10 hp motor panel - what amp ratings are offered?
Three motor FLA sizes are offered: 12A (LC1D12BL), 40A (LC1D40BD) and 65A (LC1D65ABBE). Size it off the motor's full load amps from the nameplate, not the horsepower alone. The 12A frame is rated up to 12A/690V AC-3, which is 5.5kW at 400V AC-3; step up to the 40A or 65A part as the FLA climbs.
3) Can I use this Square D contactor for a reversing motor starter?
No. The LC1D units here are nonreversing, 3-pole with 3 normally open contacts. A reversing starter needs two contactors mechanically and electrically interlocked, so you would order a pair plus the interlock kit, or a factory reversing assembly. For single-direction starting, one of these plus overload protection is the standard build.
4) Is the Square D TeSys Deca contactor UL Listed and acceptable for a code-compliant motor starter?
It is UL Listed and CSA certified, and built to IEC 60947-4-1 / EN 60947-4-1 for motor starter construction. It also carries CCC, EAC, UKCA and CB Scheme certification, which matters if the panel ships internationally. That combination is what an inspector or a plan reviewer looks for on an industrial control panel.
5) Does this Square D contactor have a high enough short circuit rating for my panel's available fault current?
The TeSys Deca LC1D is rated up to 100kA SCCR, which covers most industrial services. Remember the panel's SCCR is set by the combination of contactor and upstream protective device, so match it to the branch protection listed in the manufacturer's combination tables rather than assuming 100kA on the assembly.
6) Does the Square D LC1D contactor come with an overload relay or auxiliary contacts?
No. It is a bare 3-pole contactor with 3 NO power poles only. A complete motor starter needs a separately ordered thermal or electronic overload relay, and any auxiliary NO/NC contacts for interlocks or run feedback are add-on blocks. If you want a contactor that ships with an auxiliary contact already on it, the ABB AF16 3-pole is offered with a 1NO auxiliary contact.
7) Is the Square D LC1D contactor DIN rail mount or panel mount?
Both. It is an open-style device built for OEM and panel-builder work, with plate or rail mounting support. Open style means no enclosure is included, so it goes inside an existing control panel or enclosure rather than being mounted on a wall by itself.
8) Can this contactor switch heater banks or other resistive loads, not just motors?
Yes. Utilization categories covered are AC-1, AC-3, AC-3e and AC-4, so it handles resistive and lightly inductive AC-1 loads like heaters as well as squirrel cage motor starting (AC-3) and plugging or inching duty (AC-4). Derate to the AC-1 current rating when the load is resistive rather than using the motor FLA figure.
9) What is the difference between the Square D TeSys Deca and the ABB AF16 contactor?
The key split is the coil. The TeSys Deca LC1D units here use a fixed 24V DC coil, so the panel needs a 24V DC control supply. The ABB AF16 is a 3-pole contactor with a 100-250VAC/DC wide-band control coil, meaning one part covers both AC and DC control voltages across that range. Pick the ABB if your control voltage is 120V AC or varies between panels; pick the TeSys Deca if you are standardizing on 24V DC control.
10) I need a contactor with a built-in auxiliary contact for a run indicator - does the Square D TeSys Deca LC1D come that way?
The Square D TeSys Deca LC1D contactors are configured 3 NO - three normally open power poles for the motor circuit. If you want an auxiliary contact supplied as part of the contactor itself, the ABB AF16 3-pole is built with a 1NO auxiliary contact included, which gives you a dry contact for a run light or PLC feedback without adding a side- or front-mount auxiliary block.
11) My motor draws more than 16A - is the ABB AF16 or the Square D TeSys Deca the right frame?
The Square D TeSys Deca LC1D line covers a wider current range on a single family. It is offered in 12A, 40A, and 65A motor FLA ratings, so a motor above the AF16 frame stays within the TeSys Deca platform rather than moving you to a different series. All three are nonreversing 3-pole open-style units with a 24VDC coil, which means the control scheme and coil supply stay the same as you step up frame size across a panel.
12) Is the Square D TeSys Deca contactor safe to mount in an open control panel for touch protection?
The front face is IP20 per IEC 60529, which is finger-safe against contact with live parts from the front but offers no protection against water or fine dust. It still has to live inside a suitable enclosure; the IP rating of the assembly comes from that enclosure, not from the contactor.
13) How much heat does a TeSys Deca contactor add to an enclosure thermal calculation?
Heat dissipation is listed at 0.5 W, so it contributes very little to the enclosure heat load compared with drives or power supplies. Average life duration is stated at 20 years, which is the figure to use when planning panel refurbishment cycles.
14) Do Square D TeSys Deca contactors meet RoHS and halogen-free requirements for our sustainability spec?
They are RoHS EUR compliant, mercury free, toxic heavy metal free, and use halogen-free plastic parts and cables. Packaging is made with recycled cardboard. Worth noting for maintenance planning: the unit is listed as not serviceable, so a failed contactor is replaced rather than rebuilt with new contact kits.
