A Bulletin 503L combination lighting contactor consists of a Bulletin 500L lighting contactor and a thermal magnetic circuit breaker (inverse time) mounted in a common enclosure.
Combination lighting contactors are available for applications that require combining switching and over-current protection in the same enclosure. Combination lighting contactors may be applied for industrial, highway, and area lighting applications, or where a lighting circuit may have to be disconnected for periodic maintenance.
