Square D LC1K0910B7 – Frequently Asked Questions

1) Will a Square D LC1K TeSys K contactor work with a 110V control circuit from my existing starter panel?
Yes. The LC1K TeSys K contactors are built with a 110V AC 50/60Hz coil, so they drop straight onto a 110V control circuit. Pickup and dropout happen in 10 to 20 ms. If your control transformer puts out 24V or 240V, this is the wrong coil voltage and you need a different LC1K coil version.
2) How do I pick between the 9A and 12A Square D LC1K contactor?
Match the Motor FLA to the nameplate full load amps of the motor you are switching. The LC1K comes in 9A (LC1K0910B7) and 12A (LC1K1210F7) AC-3 ratings, usable up to 440V AC. In motor power terms the family covers up to 5.5kW at 380-415V AC-3 and 3kW at 220-230V AC-3 depending on which rating you take. If your motor FLA sits above 12A, step up to a larger frame.
3) What wire size do the terminals on the Square D LC1K accept, and what torque do I use?
Screw clamp terminals take 0.75 to 4 mm2 flexible conductor or 1.5 to 4 mm2 solid, tightened to 0.8 to 1.3 N.m. In AWG terms that covers roughly 18 through 12 gauge. Heavier feeders than that will not land in this frame.
4) Does the LC1K contactor include an auxiliary contact for run status or holding circuits?
Each LC1K in this group ships with 1 NO auxiliary contact, which is what you use for a seal-in (hold) circuit, a run pilot light, or interlocking with another contactor. If your scheme needs a normally closed aux for reverse interlocking, you will need to add an aux contact block.
5) What is the closest cross-brand equivalent to the Square D LC1K TeSys K 3-pole contactor?
The ABB AF-09301013 is the nearest match in form and function. It is an AF16 3-pole contactor with a 1 NO auxiliary contact rated 9-16A AC-3, which overlaps the LC1K TeSys K 3-pole range of 9A to 12A with its own 1 NO auxiliary contact. Both are IEC-style contactors for three-phase motor switching. The difference to check before swapping is the coil: the LC1K is specified with a 110V AC 50/60Hz control circuit coil, so confirm the ABB coil voltage you order matches your control circuit.
6) Can I use an Eaton Freedom or Citation contactor kit instead of a Square D LC1K contactor?
No - those are not substitutes. The Eaton 6-44-2 Freedom Series A1 contactor kit, the Eaton 6364 Citation B1 three-pole contactor renewal kit, and the Eaton 932563 Freedom coil and contactor kit are renewal and repair parts intended to rebuild an existing Eaton contactor, not complete devices. The Square D LC1K TeSys K is a complete 3-pole contactor with a 110V AC coil, 1 NO auxiliary contact and screw clamp terminals, mountable on a plate or DIN rail. If you are replacing a whole device, choose the LC1K or another complete contactor; the Eaton kits only apply if the Eaton base they were built for is already in the panel.
7) My motor draws more than 12A. What do I use instead of the LC1K TeSys K?
The Square D LC1K TeSys K 3-pole contactor covers a Motor FLA range of 9A to 12A, with 9A and 12A build options, so a load above 12A needs a larger frame. The ABB AF-09301013 AF16 3-pole contactor is rated 9-16A AC-3 and carries a 1 NO auxiliary contact like the LC1K, which extends coverage to 16A on the same three-pole pattern. Size the contactor to the motor nameplate full-load amps and the overload relay that goes with it.
8) Can the LC1K TeSys K contactor mount on DIN rail, or does it need a panel plate?
Both. The LC1K mounts on DIN rail or screws directly to a panel plate, so it fits retrofit backplates as well as rail-populated enclosures.
9) Can I use the LC1K for a single-phase motor or a heater load instead of a three-phase motor?
The LC1K is a 3-pole, 3 NO device intended for three-phase motor circuits, but it is also rated for resistive load switching, so heater banks are a valid use. On a single-phase motor you would simply wire two of the three poles. Current still has to stay inside the 9A to 12A rating you select.
10) My existing Eaton contactor failed. Should I buy a replacement kit or a whole new contactor like the LC1K?
Depends on what failed and what frame you already have. If the Eaton unit is intact and only the contacts or coil are burned, renewal kits exist for those lines, such as the Eaton Freedom A1 contactor kit, the Citation B1 three-pole contactor renewal kit, and the Eaton Freedom coil and contactor kit for 220-240V AC 65mm frames. Those only fit the Eaton frame they are built for. A complete LC1K is the route when you are replacing the whole device or building a new panel, and it brings its own 110V coil and 1 NO aux contact with it.
11) Can the LC1K be field repaired if the contacts wear out?
No. Square D lists the LC1K TeSys K as non-serviceable, so there are no replaceable contact or coil kits for it. When it wears out you replace the device. Plan spares accordingly if the contactor is cycling hard in a process panel.
12) I need an IEC contactor for a three-phase motor but my panel is Eaton standardized. What is the alternative to the TeSys K?
The Eaton AE16 series three-phase IEC contactor/starter for motor control is the Eaton-side counterpart to the Square D LC1K TeSys K. Both are IEC-pattern three-phase motor control devices, and the LC1K is a 3-pole design conforming to IEC 60947-4-1 with UL listing. If you are matching an existing Eaton panel for spare-parts commonality, the AE16 keeps you in one brand; if the drawing calls out a TeSys K part number, the LC1K 9A or 12A Motor FLA variants are the direct build.
13) Is the LC1K touch-safe enough for a panel that non-electrical staff may open?
The LC1K carries IP2X protection per VDE 0106, which is the finger-safe rating for live terminals. That reduces accidental finger contact with energized parts, but it is not a substitute for proper panel dead-front construction or lockout procedure.
14) Does the Square D LC1K meet RoHS and REACH requirements for a government or institutional spec?
Yes. The TeSys K LC1K is RoHS compliant and REACH compliant with no Substances of Very High Concern above threshold, and it is declared mercury free and free of toxic heavy metals. Packaging is recycled cardboard with no single use plastic, and it falls under WEEE product category 5. That covers most sustainability language in institutional and public-sector submittals.
