Maximum Voltage Rating
When selecting lighting contactors, the maximum voltage rating of the
device must be considered in addition to its current rating. The table
below lists the maximum ac voltage ratings of the Types L and S lighting
contactors for ballast, tungsten and resistance loads. Lighting contac-
tors also have dc ratings which are shown below.
Class 8903 – Application Data
AC Voltage Ratings
NOTE: 600 Ampere devices are derated to 540 Amperes for resistance heating loads when aluminum wire is used.

Current Ratings
All Class 8903 lighting contactors are fully rated for tungsten, ballast and
resistance loads. This means that a contactor can be used to control a load
up to its full nameplate rating. Derating of the contactor is not necessary,
as is the standard practice with circuit breakers and fuses.
