Built on the PowerPact Q-Frame platform, it provides thermal magnetic protection for 240VAC distribution systems with a 10kA interrupting rating. This breaker is typically found in commercial and light industrial installations where dependable overload and short-circuit protection is required.\u003c\/p\u003e\n\u003cp\u003eBecause it’s an I-Line plug-on style breaker, it installs directly into compatible panelboards without modification. If you're replacing an existing QBA series unit, this model matches the original form, fit, and function specifications. The 150A rating makes it suitable for larger branch circuits and feeder applications where steady current capacity and proper fault interruption are essential.\u003c\/p\u003e\n\u003cp\u003eThe thermal magnetic trip mechanism handles both prolonged overload conditions and instantaneous short circuits. In everyday use, that means it responds to heat buildup over time while also reacting quickly to fault events. These breakers were built for long-term service and continue to be widely used in existing distribution systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e150 amp continuous current rating\u003c\/li\u003e\n\u003cli\u003e2-pole breaker for 240VAC systems (B-C phase configuration)\u003c\/li\u003e\n\u003cli\u003e10kA interrupting capacity at 240VAC\u003c\/li\u003e\n\u003cli\u003eThermal magnetic trip unit\u003c\/li\u003e\n\u003cli\u003eI-Line plug-on mounting style\u003c\/li\u003e\n\u003cli\u003ePowerPact Q-Frame construction\u003c\/li\u003e\n\u003cli\u003eMolded case design built for lasting service\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\u003ePart Number:\u003c\/strong\u003e QBA221504\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Type:\u003c\/strong\u003e QBA \/ PowerPact Q-Frame\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 150A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 240VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 10kA @ 240VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type:\u003c\/strong\u003e Thermal Magnetic\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e I-Line, Plug-On\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e B-C Phase\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 7.88 inches\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShip Weight:\u003c\/strong\u003e 3.0 lbs\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe QBA221504 is manufactured in accordance with applicable UL standards for molded case circuit breakers.
