With a 10 kiloamp interrupting rating, it provides reliable overcurrent protection for branch circuits. The quick-make\/quick-break mechanism ensures fast, positive switching action, while the common trip bar guarantees simultaneous disconnection of both poles on an overcurrent or fault event. A visible trip indication makes it easy to identify tripped breakers at a glance, supporting faster service calls and safer panel work. Licensed electricians install this breaker as a direct plug-in unit requiring no tools beyond standard panel work.\u003c\/p\u003e\n\u003cp\u003eThe THQL2145 is suited for residential and light commercial load center applications where a 45-amp, 2-pole branch circuit breaker is required. It accepts wire sizes from 8 to 3 AWG, covering common branch circuit conductors used in 240-volt appliance circuits, HVAC equipment feeds, and sub-panel ties. Its non-interchangeable, plug-in design ensures it seats correctly in compatible load centers and cannot be substituted with incompatible breaker types. The unit is also rated suitable for reverse feed applications, offering added flexibility during panel configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-make\/quick-break mechanism for positive, reliable switching action\u003c\/li\u003e\n  \u003cli\u003eCommon trip bar ensures simultaneous 2-pole disconnection on fault events\u003c\/li\u003e\n  \u003cli\u003eVisible trip indication for fast identification during service\u003c\/li\u003e\n  \u003cli\u003eRated suitable for reverse feed applications\u003c\/li\u003e\n  \u003cli\u003eAccepts 8 to 3 AWG wire for standard branch circuit wiring\u003c\/li\u003e\n  \u003cli\u003eUL Listed under file E11592\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eNon-interchangeable plug-in type designed for use in compatible load centers accepting THQL-series breakers.

De-energize and lock out the panel at the utility disconnect or main breaker before beginning any work inside the load center. Confirm wire size falls within the 8 to 3 AWG range and that terminal connections are torqued per the load center manufacturer specifications. Do not force the breaker into positions or panel types for which it is not rated.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 45 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/240 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 10 kiloamps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Plug-In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBreaker Type\u003c\/strong\u003e: Non-Interchangeable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size Range\u003c\/strong\u003e: 8 to 3 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Load Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL E11592\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: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: THQL2145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SQUARE D","offers":[{"title":"Default Title","offer_id":51284138623282,"sku":"THQL2145","price":38.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278919.jpg?v=1781069552","url":"https:\/\/voomisupply.com\/products\/square-d-thql2145-45a-2-pole-circuit-breaker-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
