The Allen-Bradley 100-E52KY400 contactor is a 52 Amps-rated large contactor from the IEC 100 Contactors series. There are 4 poles on the 100-E52KY400 contactor. The contactor also has 4 normally open auxiliary contacts. However, normally closed auxiliary contacts are not available. The main terminals on the 100-E52KY400 contactor are screw-type terminals. The main contactor terminals, the coil terminals, and the auxiliary terminals on the contactor are all IP2X rated. The electronic coil on the 100-E52KY400 contactor is rated for 48 to 130 Volts AC/DC with 50 to 60 Hertz AC frequency. At 690 Volts AC single-phase voltage and 40 degrees Celsius, the rated current for the contactor is 100 Amps. The rated isolation voltage as per the IEC standards is 690 Volts and the rated isolation voltage as per the UL and CSA standards is 600 Volts. The rated impulse withstand voltage is 6 kVA. 

The Allen-Bradley 100-E52KY400 contactor complies with the electromagnetic compatibility requirements for the IEC 609470 standards. The insulation class of the coil on the 100-E52KY400 contactor is Class F as per the IEC 60947-4-1 standards. The rated coil frequency is 50 to 60 Hertz for the AC voltages. The ambient requirements include a -76 to 176 degrees Fahrenheit storage temperature range, a -40 to 158 degrees Fahrenheit operating temperature range, and a maximum installation altitude of 3000 meters. The 100-E series contactors such as the 100-E52KY400 contactor comply with multiple standards, including the EAC, RCM, KC, CE, CCC, CSA, and UL standards. Optional accessories including terminal shields, connecting bars, mechanical interlocks, terminal lugs and front/side-mounted auxiliary contacts can be ordered from Allen-Bradley. The 100-E52KY400 contactor is made from environmentally friendly materials. Only trained personnel should install and operate the contactor and associated machinery.
