Product DescriptionThe EATON B230AN is a single-phase thermal overload relay designed to protect motors and electrical equipment from sustained overcurrent conditions. Thermal overload relays sense excess heat generated by abnormal current draw and trip the circuit before damage occurs. The B230AN measures 1.3 inches, making it a compact unit suited for panel and starter assemblies where space is limited. This device is installed by licensed electricians and control panel technicians in both residential and light commercial electrical systems.The B230AN is a single-phase unit appropriate for use in motor starter assemblies, control panels, and similar electrical enclosures. It is typically applied where individual-phase overload protection is required on smaller motor loads. The compact 1.3-inch form factor fits standard starter frames that accept Eaton B-line overload relays.Key FeaturesSingle-phase thermal overload protection for motor circuitsCompact 1.3-inch size for space-constrained panel installationsBimetal thermal sensing element trips on sustained overcurrentDesigned for use in standard motor starter configurationsCompatibilityDesigned as an OEM-style replacement thermal overload relay for single-phase motor starter assemblies accepting Eaton B-line series overload elements.Installation NotesInstallation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or starter assembly before servicing or replacing the overload relay. Verify the replacement relay matches the overload class and trip rating required by the motor nameplate. Do not energize the system until the relay is fully seated and all covers are secured.Technical SpecificationsPhase: Single PhaseSize: 1.3 inchesWeight: 0.25 poundsUPC: 78211415505Standard InformationBrand: EATONManufacturer Part Number: B230AN
