The Allen-Bradley/Rockwell Automation 100-E09KN01 contactor is a compact and energy-efficient contactor from the Bulletin 100-E product line in the Allen-Bradley IEC 100 Contactors series. This compact contactor comes with a surge suppressor for its AC and DC coils and it can operate with AC or DC voltage. Its operating voltage range for both AC and DC voltage is from 250 to 500 Volts, and the AC voltage range includes an operating frequency range of 50 to 60 Hertz. The 100-E09KN01 contactor cannot support an optional integrated PLC interface without interposing relays, but it does support reversible coil terminations on the line side and the load side and no disassembly is required for reversing the terminations. Additionally, the auxiliary contacts for the 100-E09KN01 contactor can be front-mounted or side-mounted.

The Allen-Bradley/Rockwell Automation 100-E09KN01 compact contactor from the IEC 100 Contactors series meets the RCM, EAC, CCC, CE, and cULus standards. It is commonly used in alternative energy applications, bypass applications, and in common isolation applications because it is energy-efficient and compatible with both AC and DC voltage. The 100-E09KN01 compact contactor can accommodate electronic and pneumatic timing relays for special applications as long as they have current ratings between 9 and 97 Amps. The Bulletin 100-E contactors like the 100-E09KN01 compact contactor are some of the larger contactors that are manufactured by Allen-Bradley in the IEC 100 Contactors series, but they still save panel space with reduced weight and reduced widths compared to previous contactor models, and because they are all equipped to handle as many applications and functions as possible without specialized accessories or other modules.
