The QDA221751 PowerPacT Q circuit breaker is built to take that worry off your plate—delivering dependable overcurrent protection where it matters most. Designed for 240VAC distribution systems, this 175 amp, 2-pole breaker combines proven thermal-magnetic protection with a practical, installer-friendly design. It reacts quickly to overloads and short circuits, helping prevent equipment damage and costly downtime. And with a 25kA interrupting rating, it's more than capable of handling serious fault conditions in commercial and industrial environments. What makes this breaker especially appealing in the field is its I-Line mounting system, which simplifies installation and helps save time inside the panel. Add in the push-to-trip button for quick testing, and you've got a breaker that doesn't just protect—it makes maintenance easier too. Whether you're upgrading existing gear or building out a new system, the QDA221751 is a solid, no-nonsense choice that professionals rely on every day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart, Reliable Protection – \u003c\/strong\u003eThermal-magnetic trip responds accurately to both overloads and short circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandles High Fault Currents – \u003c\/strong\u003e25kA interrupting rating gives you confidence in demanding environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e175 Amp Capacity – \u003c\/strong\u003eBuilt for consistent performance in commercial and industrial loads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFaster Installation with I-Line Design – \u003c\/strong\u003eHelps reduce labor time and simplifies panel integration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In Push-to-Trip Button – \u003c\/strong\u003eMakes testing and maintenance quick and straightforward\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade for Real-World Use – \u003c\/strong\u003eDesigned to perform reliably through repeated operation cycles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHACR Rated – \u003c\/strong\u003eSuitable for HVAC and refrigeration systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e QDA221751\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e PowerPacT Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 175A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2 Pole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 240VAC (50\/60 Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 25kA at 120\/208V AC and 240V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type:\u003c\/strong\u003e Thermal-Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Trip Level:\u003c\/strong\u003e 2400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Rating:\u003c\/strong\u003e 80%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e I-Line (line), mechanical lugs (load)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e AB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 6.47\" H x 3\" W x 3.93\" D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e Up to 1,000 loaded cycles \/ 5,000 no-load cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis breaker is built to meet strict safety and performance standards, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUL Listed\u003c\/li\u003e\n\u003cli\u003eCSA Certified\u003c\/li\u003e\n\u003cli\u003eNOM Compliant\u003c\/li\u003e\n\u003cli\u003eIEC Certified\u003c\/li\u003e\n\u003cli\u003eMeets NEMA standards\u003c\/li\u003e\n\u003cli\u003eThat means you're not just getting performance—you're getting equipment that meets recognized industry requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe QDA221751 fits right into environments where reliability isn't optional:\u003c\/li\u003e\n\u003cli\u003eCommercial buildings and office power distribution\u003c\/li\u003e\n\u003cli\u003eIndustrial facilities and manufacturing equipment\u003c\/li\u003e\n\u003cli\u003eHVAC and refrigeration systems\u003c\/li\u003e\n\u003cli\u003eI-Line panelboards and distribution setups\u003c\/li\u003e\n\u003cli\u003eAny application requiring dependable 240VAC circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
