The product code 100-D110KL11 designates one of the contactor models that are available through the Bulletin 100-D series of industrial contactors that are manufactured by Allen-Bradley/Rockwell Automation. This Bulletin 100-D contactor is built for industrial applications and it has a protective housing that is manufactured from highly resistant materials that are made to be used in an industrial setting. The unit is not rated for protection from high levels of dust, but important parts such as the auxiliary contacts and terminal blocks have higher degrees of protection against dust, debris, and moisture. Additionally, the 100-D110KL11 contactor is protected from accidental contact according to the VDE 0106 (part 100) standards and it also has a moderate level of resistance to shock and vibration. The unit can be installed in industrial environments with a maximum altitude of 2000 meters and it is in compliance with the IEC 60068-2-30 standard for climatic withstand. 

All contactor units from the Allen-Bradley/Rockwell Automation 100-D series like the 100-D110KL11 contactor have an IEC rated isolation voltage of 1000 Volts and a UL and CSA rated isolation voltage of 600 Volts. In addition to that, the 100-D110KL11 contactor features a rated impulse voltage rating of 12 kilovolts and a rated AC voltage frequency of 50 or 60 Hertz. The 100-D110KL11 contactor has a current rating of 110 Amps and it has a 3-pole design with 3 main contacts. The unit has a conventional coil and it is a non-reversing type of contactor intended for AC applications. The AC motor output power ratings that it supports are different for each supported voltage rating and the output can be in kilowatts or in Horsepower. The included auxiliary contacts are 1 normally open auxiliary contact and 1 normally closed auxiliary contact. In addition to that, the coil voltage of the 100-D110KL11 contactor is in the range of 220 to 230 Volts.
