Square D 8903LO20V02 – Frequently Asked Questions

1) Will the Square D 8903LO lighting contactor handle a 277/480V or 600V lighting circuit?
The 8903LO Type L contactor is rated to 600V, so it covers 120, 277, 347 and 480V lighting branch circuits within its current rating. Load ratings are 30 A for fluorescent (ballast) loads and 20 A for tungsten (incandescent) loads, so size by the load type, not just the breaker.
2) What coil voltage does the Square D 8903LO contactor use, and can I drive it from a standard 120V lighting panel control circuit?
Coil is 110 V AC at 50 Hz / 120 V AC at 60 Hz, so a standard 120V control circuit from a time clock, photocell or BAS relay drives it directly with no control transformer. Hold-in draw is 30 VA; inrush is 140 VA at 50 Hz and 150 VA at 60 Hz, which is what your control contacts and control-circuit fusing have to carry at pull-in.
3) How many poles can I get on the Square D 8903L Type L contactor?
Pole counts run from 2 up to 12 on the 2/6/12-pole models (8903LO20V02, 8903LO60V02, 8903LO0012V02), plus a 10-pole unit, the 8903LO0010V02. Order by the number of switched lighting circuits, not by amperage; every pole carries the same 30 A fluorescent / 20 A tungsten rating.
4) Can I use this contactor to switch a 30A incandescent or stage tungsten load?
No. Tungsten load rating is 20 A per pole, not 30 A; the 30 A figure applies to fluorescent loads. For a 30 A incandescent circuit you need a larger contactor. Tungsten inrush is what drives the derate.
5) What is the difference between the Square D 8903LO Type L contactor and the Eaton A202 lighting contactor?
The Square D 8903LO Type L is an electrically held lighting contactor, meaning the coil stays energized to hold the contacts closed, and it is field convertible between electrically and mechanically held operation. The Eaton A202 is magnetically latched, so it holds its state without continuous coil power. Both are used for lighting control at 30A; the Square D 8903LO carries a 30A amperage rating and is rated to 600V. Choose the electrically held 8903LO where a maintained control signal from a lighting panel is the control scheme, and the latched A202 where a momentary pulse from a time clock or control relay is used.
6) I need more than three poles for a lighting control panel - which contactor covers that?
The Square D 8903LO Type L covers higher pole counts: models are offered in a 10 pole configuration (8903LO0010V02) and in 2/6/12 pole configurations (8903LO0012V02, 8903LO20V02, 8903LO60V02). The Eaton A202 is a 3-pole contactor. For a multi-circuit lighting panel where each branch needs its own switched pole, the multipole 8903LO Type L is the one to spec.
7) Does the 8903LO come with an enclosure, or do I need to mount it in a panel?
Open style only, no enclosure. It is built to drop into a panelboard, switchgear section or a separately supplied NEMA enclosure. Wiring is screw-clamp terminals, so field conductors land directly without adding lugs.
8) Is the Square D 8903L contactor acceptable for a federal or government job with TAA and Buy American type requirements?
It is TAA compliant and made in Mexico, a TAA designated country, so it clears Trade Agreements Act procurement. It is also UL Listed and CSA certified, plus RoHS compliant and mercury free for facilities with environmental purchasing rules.
9) What is the difference between the Square D 8903LO and the Eaton A202 lighting contactor?
Both are 30 A lighting contactors, but they hold differently. The 8903LO Type L is electrically held (field convertible to mechanically held) and open style, offered from 2 up to 12 poles. The Eaton A202 is magnetically latched and 3-pole at 30 A. Pick the Square D when you need high pole counts in a panel and maintained-contact control; pick the latched Eaton for a small three-circuit job driven by momentary pulses.
10) Is the Eaton A202 a drop-in replacement for a Square D 8903LO Type L?
No. They are not interchangeable as-installed. The Square D 8903LO Type L is an electrically held, open-style multipole contactor with screw-clamp terminals, built in pole counts up to 12, and rated to 600V. The Eaton A202 is a 3-pole magnetically latched contactor, so the control wiring differs - a latched unit expects momentary on and off pulses rather than a maintained coil circuit. Swapping one for the other means rework of both the power pole count and the control scheme.
11) For a federal or government lighting project, which contactor meets procurement requirements?
The Square D 8903LO Type L is TAA compliant, UL Listed, and CSA certified, which is what most federal and government specifications call for on lighting control gear. It is built in Mexico. The Eaton A202 is a magnetically latched 3-pole lighting contactor in the A202 series, but for a TAA-driven purchase the 8903LO Type L is the one that states that compliance.
12) Will the 8903LO contactor hum or buzz in an occupied space?
Square D specifies the Type L electrically held design as silent operating, which is why it gets used in offices, schools and retail where the panel sits near occupied areas. If the room is very quiet and you want zero coil noise and zero standby draw, convert it to mechanically held operation or specify a latched contactor instead.
