Square D LP4K0901BW3 – Frequently Asked Questions

1) What size motor will the Square D LP4K0901BW3 contactor handle?
The LP4K0901BW3 is a 9A AC-3 contactor, which covers motors up to 4kW at 380-415V AC-3 and 2.2kW at 220-230V AC-3 in three-phase service. Above those ratings you need a larger frame. The AC-3 current rating applies up to 440V.
2) Does this Square D TeSys K contactor take a 24V DC coil or AC?
DC only. The LP4K0901BW3 has a low-consumption 24V DC control coil with a built-in bidirectional peak limiting diode suppressor, so you do not need to add an external surge module on the coil. Feeding it 24V AC is not what this part is built for - order the AC-coil version of the series instead.
3) Does the LP4K0901BW3 come with an auxiliary contact, or do I have to add a block?
One NC auxiliary contact is built in, usable for interlocking or signaling. The power poles are 3NO. If your control scheme needs an NO auxiliary for a seal-in circuit, you will need an add-on block, since the integral contact here is normally closed.
4) Is this Square D contactor UL listed for a control panel going into a US facility?
UL Listed and CSA Certified, conforming to UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1 and No 60947-5-1, plus CE and EN/IEC 60947-4-1. Rated insulation voltage is 600V per UL 508 and 690V per IEC 60947-4-1, with an 8 kV impulse withstand.
5) I need a replacement for an existing LP4K contactor in a panel - will this one drop in?
The LP4K0901BW3 carries the LP4K compatibility code, so it sits in the same TeSys K accessory and mounting family. Match three things on the old unit before swapping: 3-pole 3NO power configuration, 24V DC coil, and the 1 NC auxiliary. A unit with a different coil voltage or an NO aux will not behave the same in your control circuit.
6) What is the closest IEC alternative to the Square D LP4K0901BW3 contactor from another brand?
The ABB AF-09301013 is the nearest match in form and function: it is an AF16 3-pole contactor rated 9-16A AC-3 with a 1NO auxiliary contact. The Square D LP4K0901BW3 is also a 3-pole contactor rated 9A AC-3 at 440V, but its built-in auxiliary contact is 1 NC rather than 1 NO. If your control circuit relies on a normally closed contact for interlocking or signaling, the Square D unit provides that directly, while the ABB unit gives you a normally open contact instead. Coil voltage must also be confirmed separately - the Square D is a 24V DC coil with a built-in bidirectional peak limiting diode suppressor.
7) Can I use an Eaton Freedom coil and contactor kit instead of ordering a whole LP4K0901BW3 contactor?
No - those serve different purposes. The Eaton 932563 is a Freedom coil and contactor kit rated 220-240V AC for a 65mm frame, and the Eaton 6-44-2 is a Freedom Series A1 contactor kit sold as a motor control renewal part. Both are replacement components intended to rebuild an existing Eaton contactor already mounted in a panel. The Square D LP4K0901BW3 is a complete 3-pole contactor, 9A AC-3 at up to 440V, with a 24V DC coil and rail or plate mounting. If you are building a new panel or replacing a failed device outright, you need the complete contactor, not a renewal kit - and the kits are frame-specific to Eaton bodies, so they will not fit a TeSys K.
8) What should I use if my load draws more than 9 amps?
The Square D LP4K0901BW3 is rated 9A AC-3 at up to 440V, which covers motors to 4kW at 380-415V AC-3 and 2.2kW at 220-230V AC-3. For a higher draw, the ABB AF-09301013 is an AF16 3-pole contactor rated 9-16A AC-3 and carries a 1NO auxiliary contact. Size to the motor full-load amps in the AC-3 column rather than to the nameplate horsepower alone, and confirm the coil voltage matches your control circuit before you order.
9) What wire size and torque do the terminals on this TeSys K contactor take?
Screw clamp terminals accept 0.75-4 mm2 flexible wire without a cable end, or 1.5-4 mm2 solid, tightened to 0.8-1.3 N.m. Worth checking against your panel schedule before you land conductors - anything heavier than 4 mm2 will not terminate.
10) Can I DIN rail mount this contactor, or does it have to be screwed to the backplate?
Either. The TeSys K 9A contactor supports rail or plate mounting, so it drops onto DIN rail in a control cabinet or bolts directly to a sub-panel.
11) What are the alternatives to the Square D TeSys K 9A contactor from other brands?
In the same 3-pole IEC class, ZenSupply carries the ABB AF-09301013 (AF16 series, 9-16A AC-3) with a 1NO auxiliary rather than the NC contact on the Square D, and the Eaton AE16 Series three-phase IEC contactor/starter. For repairing an existing Eaton assembly rather than buying new, the Freedom A1 contactor kit and the Citation B1 three-pole contactor renewal kit are rebuild parts, not standalone contactors.
12) I need a three-phase IEC contactor for a motor starter - how does the Eaton AE16 compare to the Square D LP4K0901BW3?
The Eaton AE16 Series is a three-phase IEC contactor/starter for motor control, so it addresses the same class of application as the Square D LP4K0901BW3, a 3-pole contactor rated 9A AC-3 at up to 440V conforming to IEC 60947-4-1. The practical difference for a panel builder is the control side: the LP4K0901BW3 is specified with a 24V DC coil and a 1 NC built-in auxiliary contact, and it accepts screw clamp terminals at 0.75-4 mm2 flexible or 1.5-4 mm2 solid. If your control transformer is 24V DC and you want the NC interlock contact already on the device, the Square D unit covers both without add-on blocks.
13) My existing three-pole contactor failed and it is an Eaton Citation - do I buy the B1 renewal kit or the Square D TeSys K?
If the mounted device is an Eaton Citation and the body and base are sound, the Eaton 6364 Citation B1 three-pole contactor renewal kit rebuilds it in place. Swapping to the Square D LP4K0901BW3 means replacing the whole device: it is a 3-pole contactor rated 9A AC-3 at up to 440V with a 24V DC coil, screw clamp terminals, and rail or plate mounting, so you would need DIN rail or a mounting plate and a 24V DC control source rather than reusing the existing AC coil wiring. The renewal kit keeps the existing footprint and control voltage; the TeSys K is the choice when you are standardizing the panel on IEC 60947-4-1 devices with a 24V DC control circuit.
14) Which of these contactors is UL listed for a panel going into a US commercial building?
The Square D LP4K0901BW3 is UL Listed and conforms to UL 60947-4-1, UL 60947-5-1, CSA C22.2 No 60947-4-1 and EN/IEC 60947-4-1, with a rated insulation voltage of 600V per UL 508 and 690V per IEC 60947-4-1 and an 8 kV impulse withstand. That combination is what an inspector looks for on a 3-pole motor control device in a US commercial control panel. If you are standardizing a facility on one device, the LP4K0901BW3 also publishes 30 Mcycles mechanical durability and 1.3 Mcycles electrical durability at 9A AC-3 up to 440V, which lets you plan replacement intervals across the panel.
15) How many switching cycles will a TeSys K 9A contactor last for in a duty-cycling application?
Mechanical durability is 30 Mcycles; electrical durability is 1.3 Mcycles at 9A AC-3 up to 440V. Lighter loads than full AC-3 current extend the contact life; frequent full-load motor starting works it toward the 1.3 Mcycle figure.
16) Can this contactor switch resistive loads like heaters, not just motors?
Yes, the TeSys K 9A unit is built for motor control and resistive load switching. Typical uses are motor control circuits, OEM and panel builder assemblies, and panelboard and control cabinet wiring. Size resistive loads against the AC-1 behavior of your application, not the 9A AC-3 motor figure.
