Heater elements set the thermal trip threshold by generating heat proportional to motor current draw. When current exceeds the rated level for a sustained period, the relay trips and protects the motor from damage due to overload, locked rotor, or phase imbalance conditions. This component is installed by licensed electricians and industrial maintenance technicians as part of a motor starter or contactor assembly.\u003c\/p\u003e\u003cp\u003eOverload heater elements like the CR123C303B are commonly used in commercial and industrial settings where motor starters require precise thermal protection. Typical applications include three-phase motor control panels, pump starters, conveyor drives, and HVAC fan motor assemblies. The heater element is selected based on the full-load amperage of the motor being protected and must be matched to the specific overload relay it serves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eProvides thermal overload protection by matching heater output to motor full-load current\u003c\/li\u003e\n\u003cli\u003eDesigned for use in thermal overload relay assemblies within motor starter panels\u003c\/li\u003e\n\u003cli\u003eReplaces a failed or improperly sized heater element without replacing the entire relay\u003c\/li\u003e\n\u003cli\u003eSized for precision trip response to sustained overcurrent conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement heater element for use in compatible ABB thermal overload relay assemblies.

De-energize and lock out the motor control panel before removing or installing any heater element. Confirm the heater element current rating matches the motor full-load amp rating per the relay manufacturer sizing chart. Do not energize the starter until the panel cover is secured and all connections are verified.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316630894\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CR123C303B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383911186738,"sku":"CR123C303B","price":34.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677475.jpg?v=1782611518","url":"https:\/\/voomisupply.com\/products\/abb-cr123c303b-overload-heater-element","provider":"Voomi Supply","version":"1.0","type":"link"}
