Part of the CR123 Series, this heater element installs inside a compatible overload relay to provide thermal overload protection calibrated for specific current ranges: 1.11 to 1.24 amps on single-phase circuits and 1.05 to 1.15 amps on three-phase circuits. NEMA 1 rated for indoor, non-hazardous environments. Electricians and industrial maintenance technicians install this component as part of motor starter assemblies in panel boards and motor control centers.\u003c\/p\u003e\u003cp\u003eThis heater element is suited for light-duty industrial and commercial motor control applications where precise thermal overload protection is required at low current ranges. It fits within NEMA-rated motor starters and overload relay assemblies used in manufacturing, HVAC mechanical rooms, pump controls, and conveyor systems. The CR123 Series is a recognized line for replacement heater elements in existing overload relay installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass 20 trip classification for motor overload protection\u003c\/li\u003e\n\u003cli\u003eSingle-phase current range: 1.11 to 1.24 amps\u003c\/li\u003e\n\u003cli\u003eThree-phase current range: 1.05 to 1.15 amps\u003c\/li\u003e\n\u003cli\u003eNEMA 1 enclosure rating for indoor, non-hazardous use\u003c\/li\u003e\n\u003cli\u003ePart of the CR123 Series heater element lineup for consistent replacement compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement heater element for CR123 Series overload relays used in NEMA-rated motor starter assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements and local codes. De-energize and lockout\/tagout the motor control circuit before removing or installing heater elements. Verify the current range stamped on the heater matches the motor full-load amperage as shown on the motor nameplate before placing the assembly back in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CR123 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Class\u003c\/strong\u003e: Class 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range (1-Phase)\u003c\/strong\u003e: 1.11 to 1.24 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range (3-Phase)\u003c\/strong\u003e: 1.05 to 1.15 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39120000\u003c\/li\u003e\n\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: cr123c131a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51620718248242,"sku":"CR123C131A","price":34.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83e6de2ea5467eb43cf1826d7486ab66.jpg?v=1787345551","url":"https:\/\/voomisupply.com\/products\/abb-cr123c131a-overload-relay-heater-class-20-nema-1","provider":"Voomi Supply","version":"1.0","type":"link"}
