Square D 8903L Series Type L Multipole Lighting Contactor, Electrically Held

The Square D 8903L Series Type L multipole lighting contactor is built for commercial and industrial lighting control panels, available across a family of pole/coil configurations from 3-Pole with a 120V coil up to 10-Pole with a 120V coil, including a 4-Pole 277V coil option and the 8-Pole 120V coil configuration — letting panel builders match the exact circuit count and coil voltage a lighting panel requires. Every configuration in the family shares the same electrically held switching action, is line rated up to 30A fluorescent and 20A tungsten at up to 600V, and ships in a NEMA 1 painted sheet steel enclosure for indoor installations. All configurations are UL Listed, CSA certified, and TAA compliant for government and institutional projects.

Key Features

  • Multiple Pole/Coil Configurations: Choose from 3-Pole (120V coil), 4-Pole (277V coil), 8-Pole (120V coil), and 10-Pole (120V coil) to match your lighting panel's circuit count and control voltage.
  • Electrically Held Operation: Type L contactors remain held in only while the coil is energized, delivering silent, low-heat lighting control across every pole configuration in the family.
  • Line Rated Current: Rated 20A tungsten and 30A fluorescent for standard lighting load switching, shared across all configurations.
  • Voltage Rating: 600V maximum line voltage with 110/120VAC or 277VAC coil options (depending on configuration selected), operating at 50/60Hz.
  • Power Consumption: Hold-in power consumption of 30VA at both 50Hz and 60Hz; inrush power of 140VA (50Hz) and 150VA (60Hz).
  • NEMA 1 Enclosure: Painted sheet steel surface enclosure suited to indoor commercial and industrial environments, standard across the series.
  • Rugged, Field-Convertible Design: Rugged construction with field-convertible functionality and no indicator signaling, common to every configuration.

Square D 8903LG30V02 – Frequently Asked Questions

1) Which pole counts and coil voltages can I get on the Square D 8903LG lighting contactor?
Four build combinations are offered on the 8903LG: 3-pole with a 120V coil (8903LG30V02), 4-pole with a 277V coil (8903LG40V04), 8-pole with a 120V coil (8903LG80V02), and 10-pole with a 120V coil (8903LG1000V02). Pole count and coil voltage are tied together, so if your control circuit is 277V, the 4-pole unit is the one that matches.
2) Will an electrically held lighting contactor stay closed if the control power drops?
No. The 8903L Type L is electrically held, meaning the poles stay closed only while the coil is energized. Lose control power and the contacts drop open and the lights go out. If you need the lighting to stay on through a control-power interruption or you are switching from momentary pushbuttons, you want a mechanically held contactor instead.
3) How many amps of lighting load can the Square D 8903L switch per pole?
Each pole is rated 30A for fluorescent loads and 20A for tungsten, at up to 600V. Tungsten and other incandescent loads draw heavy inrush, which is why the rating drops to 20A. Size to the tungsten figure if you are switching incandescent or anything with a similar inrush profile.
4) Can I mount the 8903L contactor outdoors or in a wet area?
Indoors only. The 8903L ships in a NEMA 1 painted sheet steel surface enclosure, which is general-purpose and offers no protection against rain, washdown, or dust. For an exterior wall, a parking structure, or a mechanical room subject to moisture, you need a NEMA 3R or 4 enclosure rating instead.
5) What control transformer or control circuit capacity do I need to pull in the 8903L coil?
The coil draws 140VA inrush at 50Hz and 150VA at 60Hz, then settles to 30VA hold-in at either frequency. Size the control transformer or the timeclock/photocell contact rating to the inrush figure, not the hold-in. The 120V coil versions operate at 110/120VAC, 50/60Hz.
6) Can an ABB AF16 3-pole contactor be used in place of a Square D 8903L lighting contactor?
They are not interchangeable in a multipole lighting panel. The ABB AF16 is a 3-pole contactor with a 1NO auxiliary contact and a 100-250VAC/DC control circuit, which is a wide-band control input suited to motor and general power switching. The Square D 8903L Type L is a lighting contactor rated 30A fluorescent and 20A tungsten at 600V, offered in 3-pole, 4-pole, 8-pole and 10-pole builds with either a 120V or 277V coil, and it ships in a NEMA 1 painted sheet steel enclosure. If the job needs more than three switched lighting circuits, or a 277V coil tapped off the lighting branch, the 8903L is the part that covers it. If the requirement is a single 3-pole open contactor with an auxiliary contact and a control voltage that may land anywhere from 100 to 250V, the AF16 addresses that instead.
7) Is the Square D 8903L contactor acceptable on a federal or government-funded project?
Yes. The 8903L is TAA compliant, which is the usual requirement on federal and government-funded work, and it is also RoHS compliant. It is UL Listed and CSA certified, so it satisfies both US and Canadian inspection. Country of origin is Mexico.
8) Can I use the 8903L lighting contactor on a 480V or 600V lighting circuit?
Yes. The load side is rated to 600V maximum, so 277/480V and 347/600V lighting circuits are within rating. Note the coil is a separate circuit: the 120V coil versions need a 120V control source, and the 4-pole unit takes a 277V coil, so on a 480V system you will typically feed the coil from a control transformer or from a 277V leg depending on which version you order.
9) Is the 8903L a motor contactor, or strictly for lighting?
It is a lighting contactor. The ratings published for the 8903L Type L are lighting load ratings, 30A fluorescent and 20A tungsten, not horsepower ratings. For motor switching you want a general-purpose IEC or NEMA motor contactor such as the ABB AF16 3-pole with a 1NO auxiliary and 100-250VAC/DC control, which is built for that duty.
10) How many lighting branch circuits can one 8903L unit control?
One pole switches one circuit, so the 8-pole unit handles eight lighting circuits from a single enclosure and the 10-pole handles ten. If you only have three or four circuits to switch off a timeclock, the 3-pole or 4-pole versions keep the enclosure and the control wiring smaller.
11) I only need to switch three lighting circuits - is there a simpler option than the 8-pole 8903L?
Yes. The Square D 8903L is built in a 3-pole version with a 120V coil under part number 8903LG30V02, which carries the same Type L electrically held construction, 30A fluorescent and 20A tungsten rating at 600V, and NEMA 1 painted steel enclosure as the 8-pole build. A 4-pole version with a 277V coil, 8903LG40V04, is the next step up if a fourth circuit or a 277V control tap is needed. An ABB AF16 is also a 3-pole device, but its control circuit accepts 100-250VAC/DC rather than a fixed lighting coil voltage, and it carries a 1NO auxiliary contact.
12) For a federal or institutional lighting project, does the ABB AF16 meet the same approvals as the Square D 8903L?
The Square D 8903L is UL Listed, CSA certified and TAA compliant, with country of origin Mexico, which is what specifiers on government and institutional work typically need documented. The ABB AF16 is an AF Series 3-pole contactor with a 1NO auxiliary contact and 100-250VAC/DC control; for a lighting control panel where UL, CSA and TAA documentation drive the submittal, the 8903L is the part written against that requirement.
13) Is the Square D 8903L field convertible, and can it be repaired?
The Type L design is field convertible, so the unit can be reconfigured in the field rather than swapped for a different part. It carries no indicator signaling. Square D does not classify it as a serviceable item, so treat it as a replace-not-rebuild device if a pole fails.
