Designed for use in load centers, it provides overcurrent protection for branch circuits in residential and light commercial electrical systems. The non-interchangeable plug-in mounting ensures correct installation in compatible load centers. It accepts wire sizes from 8 to 3 AWG, making it suitable for a range of 240-volt branch circuit applications including HVAC equipment, water heaters, and subpanels. Licensed electricians are the primary installers for this type of breaker.\u003c\/p\u003e\u003cp\u003eThe THQL2150 is suited for residential and light commercial load centers where a 2-pole, 50-amp branch circuit breaker is required. Common applications include dedicated circuits for central air conditioning units, electric dryers, electric ranges, EV charging equipment, and similar 240-volt loads. The non-interchangeable design limits use to compatible SQUARE D load center enclosures, maintaining panel integrity and safety compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50-amp current rating for 240-volt branch circuit protection\u003c\/li\u003e\n\u003cli\u003e10-kiloamp interrupting rating for fault current protection\u003c\/li\u003e\n\u003cli\u003e1-inch plug-in mounting for straightforward load center installation\u003c\/li\u003e\n\u003cli\u003eQuick-make\/quick-break mechanism for reliable switching operation\u003c\/li\u003e\n\u003cli\u003eCommon trip bars ensure simultaneous disconnection of both poles\u003c\/li\u003e\n\u003cli\u003eEasy-to-spot trip indication for fast fault identification\u003c\/li\u003e\n\u003cli\u003eUL listed for use in Canada and the United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a non-interchangeable plug-in replacement for compatible SQUARE D load centers requiring a 2-pole, 50-amp circuit breaker.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the load center and verify absence of voltage before handling any breaker or wiring. Confirm the load center enclosure accepts THQL-series non-interchangeable breakers before installation. Follow AWG wire size requirements and torque terminal connections per the load center manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 50 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\u003eInterrupting Rating\u003c\/strong\u003e: 10 kiloamps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: 1-inch plug-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 8 to 3 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaker Type\u003c\/strong\u003e: Non-interchangeable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Load center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL listed (Canada and US)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: THQL2150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SQUARE D","offers":[{"title":"Default Title","offer_id":51283984548146,"sku":"THQL2150","price":38.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278923.jpg?v=1781065065","url":"https:\/\/voomisupply.com\/products\/square-d-thql2150-50a-2-pole-circuit-breaker-120-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
