Eaton A202K1CAM – Frequently Asked Questions
1) What is the difference between a magnetically latched lighting contactor like the Eaton A202 and an electrically held contactor?
The A202 is mechanically held closed by a latching mechanism, so the coil is only pulsed to change state instead of staying energized the whole time the lights are on. That means low standby draw, less coil heat, and no chattering or dropout on a brief power blip. An electrically held contactor, such as the Square D 8903LO Series Type L, holds its contacts closed only while the coil is energized, so the lights drop out when control power is lost. Pick latched for always-on lighting panels; pick electrically held when you want the load to fall out automatically on a power loss.
2) Will the Eaton A202 contactor fit in my lighting control enclosure?
The A202 body measures 3.31 x 3.31 x 4.38 inches (width x depth x height), which is a small footprint for a 3-pole device and fits most lighting control panels, panelboard gutters, and MCC sections with room for wire bending space. Lay it out with the 4.38 inch dimension vertical.
3) What coil voltage does the Eaton A202K1CAM lighting contactor use?
The coil on model A202K1CAM is 120V at 60Hz, so it runs off a standard control circuit fed from a 120V branch or a control transformer. If your panel runs 277V or 24V control, this is the wrong coil for it.
4) How many lighting circuits can one Eaton A202 30A contactor switch?
Three. It is a 3-pole contactor rated 30A per pole, so it switches three ungrounded conductors at once, whether that is three single-phase lighting branches or a three-phase feed to a lighting panel. Keep each pole's connected load within 30A.
5) Can I run an Eaton A202 latched contactor from a maintained wall switch or photocell?
A magnetically latched contactor wants momentary control, not a maintained contact. It takes a pulse to latch and a pulse to unlatch, so wire it to momentary on/off stations, a time clock with momentary output, or a lighting control panel designed for latching contactors. A plain maintained switch or a photocell with a maintained output needs an electrically held contactor instead, like the Square D 8903LO Series Type L.
6) What is the difference between the Eaton A202K1CAM lighting contactor and a Square D 8903LO Type L contactor?
They differ in how the contacts are held closed. The Eaton A202K1CAM is a magnetically latched contactor, meaning the mechanism holds the contacts closed with minimal continuous power draw and needs only a momentary pulse to change state. The Square D 8903LO Series Type L is a multipole lighting contactor that is electrically held, so its coil stays energized the whole time the contacts are closed. The Eaton unit is a 3-pole device rated 30A with a 120V coil at 60Hz and is CSA Certified.
7) My lighting control panel uses maintained toggle switches, not momentary pushbuttons - is the Eaton A202K1CAM the right contactor?
A maintained switch suits an electrically held contactor, because the coil is energized for as long as the switch stays closed. The Square D 8903LO Series Type L multipole lighting contactor is the electrically held design. The Eaton A202K1CAM is magnetically latched, which is intended for momentary pulse control - a pulse to close and a separate pulse to open - so it pairs with momentary pushbuttons, time clocks with pulse outputs, or photocell logic rather than a maintained toggle.
8) Is a 30A contactor enough for a warehouse or parking lot lighting circuit?
A 30A per pole rating covers the typical 20A lighting branch circuits used for warehouse, parking lot, and facility lighting, and it is common for panelboard and load center feeds in lighting control panels. For larger banks of fixtures beyond 30A per pole you need a higher ampere frame, not this one.
9) What exact part number should I order for the Eaton 3-pole 30A latched lighting contactor?
Order Eaton A202K1CAM. That is the A202 series, 3-pole, 30A, 120V 60Hz coil, magnetically latched version.
10) I need to switch more than three lighting circuits - can I use the Eaton A202K1CAM?
The Eaton A202K1CAM is a three-pole contactor, so it switches three circuits from one device; larger jobs either use multiple A202 units or a higher pole count. The Square D 8903LO Series Type L is a multipole lighting contactor from the 8903L series, which is the direction to look when a single device has to carry more poles than three.
11) Will a Square D 8903LO drop straight into the space where an Eaton A202 contactor was mounted?
Treat it as a re-layout, not a swap. The Eaton A202K1CAM occupies a compact footprint of 3.31 in wide by 3.31 in deep by 4.38 in high, and its wiring assumes pulse control of a magnetically latched mechanism. The Square D 8903LO Series Type L is an electrically held multipole contactor from a different series, so both the mounting pattern and the control wiring need to be confirmed against the panel before substituting.
