Allen-Bradley 810-A09C Inverse Time Current Overload Relay

The Allen-Bradley 810-A09C inverse-time current overload relay provides motor protection by tripping on overload current with inverse-time characteristics. Designed for use in AC motor control circuits, it is rated for 600VAC DC Max, and is part of the Allen-Bradley 810 family of protective relays known for compact, modular protection devices. In operation, the relay continuously monitors motor current and initiates a trip when an overload is detected, with trip time inversely related to the overload level to balance protection with normal motor starting and running. Typically installed in motor starter assemblies alongside a contactor to safeguard motors and wiring in industrial panels and equipment. This model is suited for integration into control schemes where reliable overload protection is required and where standard Allen-Bradley/ Rockwell Automation components are used. Typical wiring and mounting align with standard Allen-Bradley protective relay practices, allowing straightforward replacement in compatible motor control circuits.
