The 100-D110T00 contactor is an AC-powered non-reversing contactor that can be used in different automation applications that require motor control devices. This contactor can be found in the Bulletin 100-D series of contactors by Allen-Bradley/Rockwell Automation. This contactor is notable because, unlike fuses and relays, it can be used in high-voltage applications that require high switching capabilities. This specific contactor is a non-reversing contactor and so it cannot be used in reversing applications or with reversing motors. Motors that require a reversing contactor and reversing mechanisms are not compatible with this contactor. The Allen-Bradley/Rockwell Automation 100-D110T00 AC-powered non-reversing contactor operates with 2 different voltage ratings, depending on the frequency applied. With 50 Hertz frequency, the contactor can operate at 240 Volts AC, whereas with 60 Hertz frequency, it can operate at 277 Volts AC.

The Allen-Bradley/Rockwell Automation 100-D110T00 Bulletin 100-D AC-powered non-reversing contactor operates with a current rating of 110 Amps at 60 degrees Celsius. At higher temperatures (up to 70 degrees Celsius), this current value must be derated so that the contactor can function safely. The Allen-Bradley/Rockwell Automation 100-D110T00 AC-powered non-reversing contactor’s installation process is not complex and the use of additional tools is not required. It is recommended to install the contactor on a panel only. The contactor does not include any auxiliary contacts, but these can be selected from the accessories catalog. This contactor comes with 3 main contact poles and it operates with conventional coils. The contactor has been manufactured with materials that do not cause any harm to the environment but that can be damaged easily if they come into contact with corrosive materials.
