Cutler-Hammer H1038 Thermal Overload Relay & Starter Heater Element is a combined protection device for motor starters, delivering thermal overload protection in a compact unit and incorporating a starter heater element. It is rated for 10.6–14.3 A, specifying the current range the relay guards against during motor operation. Designed for inclusion in compatible motor starter assemblies, this component helps prevent motor damage from overcurrent and overheating by coordinating overload sensing with the starter’s thermal management.
