The 500L-CAD93 contactor is a Bulletin 500L lighting contactor which comes in an open NEMA Type 1 enclosure and which is designed for general purpose applications. Bulletin 500L contactors like this one are top wired and electrically held contactors that are designed for non-motor loads and lighting. The enclosures which are available for the 500L contactors include the NEMA Type 1, NEMA Type 3R/12, and NEMA Type 4/4X enclosures which are made of stainless steel. Special-purpose enclosures, including Type 4X glass reinforced polyester, bolted size 7 and 9, and 3R size 7 and 9 enclosures are also available. The 500L contactors should not be used for sign flashers. The 500L contactors are certified by the CSA, UL, and CE standards. They also comply with standards such as the IEEE 45, UL 508, and CSA C22.2 standards.

The coil on the 500L-CAD93 contactor is rated for 115 to 120 Volts AC at 60 Hertz. Even though this coil is optimized for this voltage range, it can be used at 110 Volts AC and 50 Hertz nominal voltage. The maximum service voltage rating for the 500L-CAD93 contactor is 600 Volts AC and the maximum line frequency that is supported is 60 Hertz. For general-purpose use, the current rating of the 500L-CAD93 contactor is 60 Amps. The 500L-CAD93 contactor is a 3-pole contactor. The contactor should be protected against dust, moisture, and corrosive contaminants because exposure to these elements can damage the components and affect the reliable operation of the contactor. The relevant instructions provided by Allen-Bradley should be followed during installation, maintenance, and operation. Only technicians who possess the requisite training should be involved in the installation of the 500L-CAD93 contactor.
