The 100-D115K11 IEC contactor from the Allen-Bradley/Rockwell Automation IEC 100 and Bulletin 100-D series has 5 contacts built into it. Three of its built-in contacts are its 3 main power contacts which are also known as poles, and the other 2 are side-mounted auxiliary contacts. One of the side-mounted auxiliary contacts is NC or normally closed while the other one is NO or normally open. More auxiliary contacts can be added onto the 100-D115K11 IEC contactor with side-mounted auxiliary contact blocks if necessary. The 100-D115K11 IEC contactor uses a conventional electronic coil and it has thru-hole and threaded screw-type terminals. This contactor can be customized with overload relays, terminal lugs, terminal blocks, terminal shields, terminal covers, interlocks, and device labels.

The Allen-Bradley/Rockwell Automation Bulletin 100-D 100-D115K11 IEC contactor has been certified by the UL, CE, CSA, IEC, and CCC standards. Its rated coil voltage is 24 Volts AC at a rated frequency of 50 Hertz. Using labels or marking systems to identify the 100-D115K11 IEC contactor clearly is highly recommended because it will make the contactor easy to locate and therefore easy to use and to service when required. The marking systems that can be used with the 100-D115K11 IEC contactor include self-adhesive paper labels or perforated paper labels that are protected by transparent plastic sheets. This contactor cannot be mounted on a DIN Rail, but it can be mounted on a galvanized steel plate that supports starter combinations. The 100-D115K11 IEC contactor can also be interlocked with another contactor in certain applications through interlocks which can be mechanical only or mechanical and electrical.
