The Eaton C306DN3B Overload Relay (Cutler-Hammer) is a thermal-magnetic protective device for motor circuits that uses heat-based and magnetic trip elements to interrupt current when a motor draws unsafe levels of current. It is designed to be used as part of a motor starter assembly, providing reliable overload protection within Eaton/Cutler-Hammer control systems. Identified by model C306DN3B, this unit is a thermal-magnetic overload relay intended for use in compatible Eaton motor-control configurations.
