The 100-D300EY11 contactor is a non-reversing contactor from the Bulletin 100-D series from Allen-Bradley/Rockwell Automation. It is an MCS contactor that conforms to the IEC standards. It is a member of the Allen-Bradley Bulletin 100-D contactor family, which features space-saving, cost-saving, and energy-saving contactors. The 100-D300EY11 non-reversing IEC contactor has an operating current rating of 300 Amps at 690 Volts and 60 degrees Celsius. It comes with 3 main contact poles and an electronic coil with an electronic interface built in. At 50/60 Hertz coil frequency, the coil's rated voltage range is 42 to 64 Volts AC. The 100-D300EY11 contactor includes one external N.O. side-mounted auxiliary contact and one external N.C. side-mounted auxiliary contact. If the application demands it, optional 2-pole auxiliary contact blocks can be added on the side of the contactor. The optional contact blocks have to be ordered separately from the main contactor. 

The Allen-Bradley 100-D300EY11 Bulletin 100-D contactor comes with an AC-1 current rating of 450 Amps at 690 Volts and an ambient temperature of 40 degrees Celsius.  The contactor's 3-phase output power ratings at 50 Hertz frequency are 97 kilowatts at 230 Volts, 170 kilowatts at 400 Volts, 185 kilowatts at 415 Volts, 213 kilowatts at 500 Volts, and 293 kilowatts at 690 Volts. In accordance with the IEC 60072-1 standards, the output power ratings at 50 Hertz are the preferred values for motor control applications. The contactor’s main current circuit has a resistance rating of 0.18 milliohms, and its AC coil dissipates 54.6 Watts at 400 Volts AC-3. The short circuit rating (SCCR) of the contactor per the IEC standards is 500 Amps for Type 2 coordination. The 100-D300EY11 non-reversing contactor complies with the IEC, CSA, and UL international standards, and it is CE and CCC certified.
