This thermal overload heater fits into compatible overload relay assemblies and generates calibrated heat proportional to current flow. When current exceeds the rated threshold, the bimetallic trip mechanism activates, interrupting the control circuit before motor windings sustain damage. Installation is typically performed by licensed electricians and industrial maintenance technicians working on motor starter and contactor assemblies. The unit weighs 0.02 pounds and measures 1.5 inches long by 0.5 inches wide by 1.25 inches tall, making it a compact, direct-fit replacement component.\u003c\/p\u003e\n\u003cp\u003eHeater overload elements like the CR123C356A are used in residential, commercial, and light industrial motor control centers, across applications including HVAC compressor starters, pump motor starters, and conveyor drive assemblies. They are installed inside thermal overload relays mounted on contactor bases. Each pack contains one element, allowing technicians to replace individual heaters within a multi-pole relay assembly as needed rather than replacing the entire relay.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal heater element sized for calibrated overcurrent trip response in compatible overload relays\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 1.5 x 0.5 x 1.25 inches for direct-fit installation\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.02 pounds for easy handling in tight panel enclosures\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-element replacement without full relay swap\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in motor starter and contactor protection circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement heater element for use with compatible ABB thermal overload relay assemblies.

De-energize and lock out the motor control panel before removing or installing any overload heater element. Verify the replacement heater element matches the amperage rating required for the connected motor load before installation. Do not energize the circuit until the relay assembly is fully reassembled and the enclosure is secured.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316630897\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: CR123C356A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383771595058,"sku":"CR123C356A","price":57.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677539.jpg?v=1782606965","url":"https:\/\/voomisupply.com\/products\/abb-cr123c356a-heater-overload-element","provider":"Voomi Supply","version":"1.0","type":"link"}
