Why Square D?

Square D engineers the TeSys Deca line to IEC 60947-4-1 and holds UL and CSA listings, giving panel builders and contractors a contactor family they can specify with confidence across the 25A and 38A FLA range. The low-consumption 24V DC coil with transient suppressor reduces energy draw and heat in the enclosure, while the 3 NO nonreversing configuration and plate/rail mounting keep installation straightforward across commercial and industrial motor control applications.

Square D LC1D25BL – Frequently Asked Questions

1) Will the LC1D-BL contactor work on a 480V three-phase motor circuit?
Yes. The power circuit on the LC1D-BL is rated up to 690V AC across 25 to 400Hz, so 480V three-phase is well inside its rating. It will also handle up to 300V DC on the power side. Published AC-3 motor power ratings are 11 kW at 380 to 400V AC and 5.5 kW at 220 to 230V AC, so size by motor FLA at 480V rather than by those kW figures.
2) What coil voltage does the Square D LC1D-BL use, and can I drive it straight from a PLC power supply?
The -BL suffix means a 24V DC low-consumption coil, so it runs off a 24VDC control supply rather than a control transformer. It ships with an integrated transient suppressor module, which is what lets it be switched from solid-state outputs without a separate diode across the coil. If your panel control voltage is 120V AC, this is the wrong coil variant.
3) Is the Square D TeSys Deca LC1D-BL acceptable for a UL panel build in the US and Canada?
Yes. The contactor is UL Listed and CSA Certified, and conforms to EN 60947-4-1, IEC 60947-4-1, CSA C22.2 No. 60947-4-1 and CSA C22.2 No. 14. It is also UKCA marked, CB Scheme, CCC, EAC and marine approved, which matters if the panel is shipping offshore or onto a vessel.
4) My motor is only about 10 amps - is there a smaller contactor than the LC1D-BL?
Yes. The ABB AF-09301013 is an AF16 three-pole contactor rated 9 to 16A in AC-3 and includes a 1NO auxiliary contact, which sits below the Square D LC1D-BL motor FLA range of 25A to 38A. Both are 3-pole designs for motor control, so for a roughly 10A motor the AF16 is the size-appropriate choice and the LC1D-BL would be oversized for the load.
5) Can I use an Eaton Freedom or Citation contactor kit in place of a Square D LC1D-BL?
No. 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 parts meant to rebuild an existing Eaton NEMA-style starter. The Square D LC1D-BL is a complete 3-pole IEC nonreversing contactor you mount on a plate or DIN rail and wire as a new device. Use the Eaton kits to service Eaton gear already in the panel; use the LC1D-BL when you are installing a contactor.
6) Can the LC1D-BL contactor be used to reverse a motor?
No. It is a nonreversing contactor with 3 NO poles, so on its own it only starts and stops in one direction. A reversing starter needs two contactors mechanically and electrically interlocked, so you would order a pair plus the reversing interlock rather than a single LC1D-BL.
7) Does the LC1D-BL mount on DIN rail or does it need a panel plate?
Either. Mounting support covers plate or rail mounting, so it drops onto DIN rail in a standard control enclosure or bolts flat to a back panel where rail space is tight. The front face is IP20 per IEC 60529, which means it is finger-safe but has to live inside an enclosure.
8) What continuous current can the LC1D-BL carry, not just motor FLA?
Thermal current (Ith) on the power circuit is 40A at 60 degrees C, with 10A at 60 degrees C on the signalling circuit. That 40A figure is the continuous carry limit for resistive or non-motor loads, which is why the motor FLA ratings (25A and 38A) sit below it.
9) Does the LC1D-BL include an auxiliary contact for a run indicator or seal-in circuit?
Contact composition is 3 NO power poles only, so there is no auxiliary contact block counted in the base LC1D-BL. If you need a seal-in or a run light, plan on an add-on auxiliary contact block. For comparison, the ABB AF16 (AF-09301013) is supplied with a 1NO auxiliary contact built in.
10) My control circuit is 230V AC, not 24V DC - what should I use instead of the LC1D-BL?
The Square D LC1D-BL uses a 24V DC low-consumption coil with an integrated transient suppressor, so it needs a DC control supply. For a 230V AC control circuit, the Eaton 932563 Freedom coil and contactor kit is rated 220-240V AC and is the AC-coil option in the comparable group. Confirm the kit matches the Eaton starter frame you are working in, since it is a coil and contactor assembly rather than a standalone IEC contactor.
11) Does the Square D LC1D-BL come with an auxiliary contact like the ABB AF16 does?
The Square D LC1D-BL is supplied as a 3-pole device with a 3 NO power contact composition and a separate signalling circuit rated 10A thermal at 60 degrees C. The ABB AF-09301013 AF16 is listed with a 1NO auxiliary contact as part of the unit. If your control scheme needs an auxiliary interlock or run-status contact on the Square D, plan on a TeSys Deca auxiliary contact block rather than assuming one is on board.
12) Which contactor should I specify if I need UL and CSA listing on the drawing?
The Square D TeSys Deca LC1D-BL is UL Listed and CSA Certified and conforms to IEC 60947-4-1, EN 60947-4-1, CSA C22.2 No. 60947-4-1 and CSA C22.2 No. 14, with marine approval and CB Scheme coverage as well. Among the cross-brand options, the ABB AF16 and Eaton AE16 are both IEC-style three-pole motor contactors, so verify the specific approvals on the catalog sheet for the exact rating you order against what your submittal requires.
13) How long should a TeSys Deca contactor last in a conveyor or pump application?
Square D publishes 30 million cycles mechanical durability and an average life duration of 20 years for the LC1D-BL. For cycling loads like conveyors, pumps and fans, that mechanical figure is the one to compare. Note that serviceability is listed as No, so the body is not rebuilt in the field, it is replaced.
14) Why choose a low-consumption 24VDC coil contactor for a packed control enclosure?
Heat and power budget. The LC1D-BL's low-consumption 24V DC coil draws less and puts less heat into the enclosure than a standard coil, which matters when you have several starters stacked in one panel and are sizing the 24VDC supply. The built-in transient suppressor also keeps coil-collapse spikes off the control wiring shared with PLC I/O.
