The 100-D140B00 contactor is an IEC 3-pole contactor in the IEC 100 and Bulletin 100-D series that has been manufactured by Allen-Bradley/Rockwell Automation. The built-in features of the 100-D140B00 IEC 3-pole contactor are basic and limited, but many new features can be added to the contactor from the IEC 100 and Bulletin 100-D accessories catalog. The 3 poles located on the top of the 100-D140B00 IEC 3-pole contactor are its only built-in contacts, but it can host different kinds of side-mounted auxiliary contacts if needed. This contactor uses a conventional coil with a somewhat high coil voltage rating of 415 Volts AC and with a corresponding coil frequency rating of 50 Hertz. This conventional coil is protected by Class B insulation.

The IEC 100 and Bulletin 100-D series 100-D140B00 IEC 3-pole contactor from Allen-Bradley/Rockwell Automation is resistant to moderate amounts of vibration and shock because it is meant to operate in applications that involve moderate amounts of vibration and shock, and it is protected from accidental contact, which means that the operators cannot accidentally touch and be injured by any of its hazardous components. However, the 100-D140B00 IEC 3-pole contactor is not strongly protected from liquids or dust, and it may need to be outfitted with protective accessories like frame terminal blocks and contactor covers in certain environments. The 100-D140B00 IEC 3-pole contactor can operate at ambient temperatures between -25 and 60 degrees Celsius under full power. If its current rating is reduced by 15%, this contactor can operate at a maximum ambient temperature of 70 degrees Celsius.
