Square D 8903LXG40V02 – Frequently Asked Questions

1) How many poles does the Square D 8903LXG lighting contactor come in?
The 8903LXG Type L is ordered by pole count in 2, 4, 6, 8, 10 and 12 pole builds. The part numbers run 8903LXG20V02 (2-pole), 8903LXG40V02 (4-pole), 8903LXG60V02 (6-pole), 8903LXG80V02 (8-pole), 8903LXG1000V02 (10-pole) and 8903LXG1200V02 (12-pole). Pick the pole count to match the number of lighting circuits you are switching, one pole per switched leg.
2) What control coil voltage does the 8903LXG contactor need?
The control circuit runs on 110V AC at 50Hz or 120V AC at 60Hz. On a standard 120V control circuit in North America you wire straight to the coil, no control transformer needed. Inrush is 140 VA at 50Hz and 150 VA at 60Hz, with 30 VA hold-in, so size the control wiring and any timeclock or relay contacts driving it for that inrush.
3) Can the 8903LXG handle 277V or 480V lighting circuits?
Yes. The line side is rated 600V, which covers 120V, 277V single phase and 480V three phase lighting distribution. Switching capacity is 30A per pole on fluorescent (ballast) loads and 20A per pole on tungsten/incandescent, so derate your circuit selection accordingly when the load is filament lamps.
4) Can I mount the 8903LXG outdoors or in a wet area?
No. It ships in a NEMA 1 painted sheet steel enclosure, which is indoor general purpose only, giving protection against incidental contact and falling dirt but not water, washdown or weather. Keep it in an electrical room, mechanical room or interior lighting control closet. An outdoor or damp location needs a rainproof or weatherproof enclosure rating instead.
5) Can an ABB AF16 3-pole contactor be used in place of a Square D 8903LXG lighting contactor?
They are different classes of device. The Square D 8903LXG is a Type L mechanically held multipole lighting contactor, built so the poles stay switched without the coil being continuously energized, rated 600V and 30A with pole counts from 2 through 12. The ABB AF16 is a 3-pole contactor from the AF series with a 1NO auxiliary contact and a 100-250VAC/DC control input. For a lighting panel that needs 6, 8, 10 or 12 poles switched from a momentary control signal, the 8903LXG configuration is what matches; the AF16 3-pole is a general-purpose electrically held device with a wide-range coil, suited to motor and small load switching where three poles are enough and a maintained control signal is available.
6) My control voltage is 208V - will a Square D 8903LXG work, or do I need something else?
The Square D 8903LXG Type L is supplied with a 110/120VAC 50/60Hz control coil, so a 208V control source is outside what that coil accepts and would require a control transformer to step down to 120V. Where a wide-range control input is wanted instead, the ABB AF16 3-pole contactor takes 100-250VAC or DC on its coil, which covers 120V and 208V control without a separate transformer - with the limitation that it is a 3-pole device with a 1NO auxiliary contact rather than a multipole lighting contactor.
7) What is the difference between a mechanically held and an electrically held lighting contactor?
Mechanically held is what the 8903LXG Type L is: the coil is pulsed to latch the contacts, then the contacts stay put with no continuous coil energization. That means no coil hum, no standing power draw, and the lighting state survives a control power loss. An electrically held contactor holds its coil energized the whole time the lights are on, which is simpler to wire off a plain maintained switch but draws power continuously and drops out on a control power interruption. For timeclock, photocell or building automation pulse control of lighting panels, the mechanically held version is the usual pick.
8) Do I have to order normally closed poles separately on the 8903LXG?
No. The poles are field-convertible with N.O./N.C. indicators, so an electrician can reconfigure contacts on site rather than ordering a different device. The 6-pole build, for example, arrives as 6 NO and you convert whichever poles need to be normally closed for a night-light or exempt circuit that must stay energized when the rest of the panel drops.
9) Is the Square D 8903LXG contactor acceptable for a federal or government job?
It is TAA compliant and made in Mexico, which is a designated country for Trade Agreements Act purposes, so it clears the usual TAA requirement on federal procurement. It is also UL Listed and CSA Certified for inspection on both sides of the border.
10) Should I use a lighting contactor or a standard motor contactor for switching lighting circuits?
Use the lighting contactor. The 8903LXG Type L is rated specifically for lamp loads, 30A fluorescent and 20A tungsten per pole, because ballast and filament inrush behaves differently from a motor load. A general purpose motor-rated device like the ABB AF16 3-pole contactor from the AF Series is built around motor starting duty and tops out at three poles with an auxiliary contact, so it does not give you the six to twelve switched lighting circuits or the mechanically held latching behavior that a lighting control panel expects.
11) Will the 8903LXG work with a building automation system or timeclock?
Yes, and that is its natural application. Because it latches mechanically, the BAS, timeclock or photocell only has to supply a momentary 120VAC pulse to the coil to change state instead of holding an output on all day. Make sure the controller output is rated for the 150 VA inrush at 60Hz and that you wire both the ON and OFF control legs, since a mechanically held device needs a separate signal to unlatch.
12) I only need to switch three lighting circuits - is a 3-pole contactor like the ABB AF16 enough, or do I need the Square D 8903LXG?
A three-circuit job is within reach of a 3-pole device such as the ABB AF16, which carries three poles plus a 1NO auxiliary contact and accepts 100-250VAC or DC control. The tradeoff is holding method and control wiring: the Square D 8903LXG is mechanically held, so it does not draw coil power once latched and works from a momentary two-wire or three-wire control signal, and its smallest build is a 2-pole with 4-pole and 6-pole steps above it. If the lighting control scheme uses momentary pushbuttons, a time clock contact, or a photocell pulse, the mechanically held 8903LXG is the arrangement that suits it. If a maintained control signal is present and continuous coil draw is acceptable, a 3-pole electrically held contactor covers three circuits.
13) Does the Square D 8903LXG come in an enclosure, or is it a panel-mount unit like the ABB AF16?
The Square D 8903LXG Type L is housed in a NEMA 1 painted sheet steel enclosure, which makes it a standalone indoor lighting control assembly that can be surface mounted on its own rather than requiring a separate box. The ABB AF16 is identified as a 3-pole AF series contactor with a 1NO auxiliary contact, the form factor normally landed inside an existing panel or control cabinet. On a renovation where the contactor hangs beside the panelboard with no enclosure already in place, the NEMA 1 housing on the 8903LXG covers that need directly.
14) For a federal or government lighting project, is the Square D 8903LXG or the ABB AF16 the right specification?
The Square D 8903LXG Type L multipole lighting contactor is UL Listed, CSA certified, TAA compliant, and manufactured in Mexico, which is the documentation set most federal and institutional procurement specifications ask for on a lighting control device. The ABB AF16 is an AF series 3-pole contactor with a 1NO auxiliary contact and 100-250VAC/DC control - a different device class sized for three-pole switching. For a multipole lighting control panel on a project with TAA language in the spec, the 8903LXG is the item that answers both the function and the compliance requirement.
