Square D LC1D50AG7 – Frequently Asked Questions

1) What is the difference between the Square D LC1D50AG7 and LC1D65AG7 contactors?
Both are 3-pole TeSys Deca contactors with 120V AC 60Hz coils; the difference is motor current. The LC1D50AG7 is the 50A Motor FLA version and the LC1D65AG7 is the 65A Motor FLA version. Size it to the full load amps on the motor nameplate, not to the AC-1 rating. Across the family the AC-3/AC-3e rating runs to 65A at 440V (30kW at 400V) and AC-1 to 80A at 440V or less.
2) What coil voltage does the LC1D-AG7 contactor use?
The AG7 suffix on a TeSys Deca contactor is the 120V AC 60Hz coil. If your control circuit runs 24V DC or 240V AC, the AG7 is the wrong catalog number for that panel.
3) Is the Square D LC1D-AG7 contactor UL Listed for use in a control panel I'm building?
UL Listed and CSA Certified, and it conforms to UL 60947-4-1, IEC 60947-4-1, EN 60947-4-1 and CSA C22.2 No 14. It also carries CE, CB Scheme, EAC, UKCA, CCC and marine certification. The housing is UL 94 V1 flame retardant and the front face is IP20 per IEC 60529, which is what panel builders look for on a device behind a dead-front.
4) Does the LC1D-AG7 include overload protection for the motor?
No. It is a contactor only, a switching device with three NO power poles. Motor overload protection has to come from a separate thermal overload relay or electronic overload sized to the motor FLA, plus short-circuit protection ahead of it. The contactor supplies the AC-3 switching duty, up to 65A at 440V, and the 1NO+1NC auxiliary contacts for control interlocking.
5) Is the ABB AF16 contactor an equivalent to the Square D LC1D-AG7?
No. The ABB AF-09301013 is an AF16 3-pole contactor rated 9-16A AC-3 with one NO auxiliary contact, which is a much smaller frame than the Square D LC1D-AG7. The LC1D-AG7 TeSys Deca is a 3-pole IEC contactor offered in 50A and 65A Motor FLA versions, rated AC-3/AC-3e up to 65A/440V and AC-1 up to 80A, with built-in 1NO+1NC auxiliary contacts. Use the AF16 size only on small motor loads; for a 50A or 65A motor branch the LC1D-AG7 is the correct frame.
6) Does the Square D LC1D-AG7 contactor come with auxiliary contacts, or do I have to add a block?
One NO and one NC auxiliary contact are built in, so you can wire a seal-in circuit, a run signal, or an interlock without buying an add-on block. Additional auxiliaries would require a separate accessory.
7) Can I use this Square D contactor to switch a resistive heater load instead of a motor?
Yes. The TeSys Deca LC1D-AG7 is rated AC-1 up to 80A at 440V or less for resistive and non-inductive switching, which is the category heater banks fall under. For motor duty you use the AC-3 rating instead, which tops out at 65A/440V.
8) What voltage can the LC1D-AG7 power circuit handle?
Rated insulation voltage (Ui) is 600V under UL/CSA, with a 6kV rated impulse withstand (Uimp). That covers 480V and 600V three-phase distribution. Motor switching ratings are given at 440V and below, so confirm your motor voltage against the AC-3 data before applying it on a 600V motor.
9) Will the Square D LC1D-AG7 hold up in an unheated outdoor enclosure or a hot machine room?
Ambient rating is -40 to 60 degrees C, with derating permitted up to 70 degrees C. Durability is 6 million mechanical cycles and 1.45 million electrical cycles at 65A AC-3 up to 440V, so frequent cycling on a jog or pump application is within its design life.
10) What other IEC contactors could I use instead of the Square D LC1D-AG7?
Among other IEC-style contactors stocked, the Eaton AE16 Series three-phase IEC contactor/starter and the ABB AF16 (AF-09301013, 3-pole with a 1NO auxiliary, 9-16A AC-3) are the closest in style. Note the current: the ABB AF16 covers 9 to 16A AC-3, far below the 50A and 65A Motor FLA range of the LC1D-AG7, so it is not a replacement for a 50A or 65A motor load. The Eaton Freedom and Citation items in that lineup are coil and contact renewal kits for existing contactors, not standalone devices.
11) My existing contactor is failing. Should I buy a new LC1D-AG7 or a rebuild kit?
If the contacts are pitted but the coil and frame are sound, a renewal kit is the cheaper path, and kits exist for specific lines: the Eaton 6-44-2 Freedom Series A1 kit, the Eaton Citation B1 three-pole kit, and the Eaton Freedom 220-240V 65mm coil and contactor kit. Those only fit their own families. The Square D LC1D-AG7 is a complete new contactor, which is what you need if you are changing brands, building a new panel, or your old device is a different frame size.
12) Is the Eaton Citation B1 three-pole contactor renewal kit a substitute for the LC1D-AG7?
No. The Eaton 6364 is a Citation B1 three-pole contactor renewal kit, intended to refresh contacts in an existing Citation B1 device rather than serve as a standalone contactor. The Square D LC1D-AG7 is a standalone 3-pole TeSys Deca contactor with 1NO+1NC built-in auxiliary contacts and 120V AC 60Hz coil options, so it mounts and wires as a complete device in a new or replacement starter assembly.
13) What wire size do the control terminals on this TeSys Deca contactor take?
The control circuit uses screw clamp terminals sized for 1 to 2.5 mm2 conductors, roughly 18 to 14 AWG, which is the usual range for panel control wiring.
14) Is this a 3-pole contactor, and can I use it for single-phase?
It is a 3-pole device with three normally open power poles, intended for three-phase motor and load switching. For single-phase you would land the two line conductors on two of the three poles, which is common practice, but the device itself is built and rated as a 3P contactor.
15) How does the Eaton AE16 IEC contactor compare with the Square D TeSys Deca LC1D-AG7?
Both are IEC-style three-phase motor control devices. The Eaton AE-16LN0A is an AE16 series three-phase IEC contactor/starter. The Square D LC1D-AG7 is a TeSys Deca 3-pole contactor available in 50A and 65A Motor FLA, with 600V rated insulation voltage, 6kV Uimp, IP20 front-face protection, 6 Mcycles mechanical durability and built-in 1NO+1NC auxiliary contacts. The AE16 frame covers smaller motor ratings, so match the frame to your motor full-load amps before choosing.
