The 106D206 coil is a coil that has been designed and manufactured by Allen-Bradley/Rockwell Automation. This coil has been designed as a 106 starters series spare part and it is included in the repair parts catalog for the 509 series of non-reversing motor starters, and the 709 series of non-reversing starters from Series K or later. It is important to understand that this coil is only compatible with NEMA Size 6 contactors and starters that start with the 702-GO*,705-GO*, 709-GO* catalog numbers, and the NEMA Size 7 devices with the catalog numbers 500-HO*, 505-HO*, 509-HO*. The Allen-Bradley/Rockwell Automation 106D206 coil is used in a rectifier circuit. This coil is powered by the AC input that is provided by the starter. It is not recommended to connect this coil to a DC control input voltage source that is completely external to the starter.

The Allen-Bradley/Rockwell Automation 106D206 coil and the contactors that are compatible with it have been designed for commercial and industrial applications that require space conservation. The NEMA enclosure provided by the starter and contactor will protect this coil from external particles that could cause internal damage if they entered the starter and that would require invasive maintenance procedures to remedy. The Allen-Bradley/Rockwell Automation 106D206 coil is made to be part of a control panel that contains a rectifier circuit and other components. It is recommended to have a technician perform the installation because it is a complex process. The whole control panel with all its components will determine the voltage level that needs to be provided to the contactor or starter according to their specifications.
