The QOB3301021 is designed to match those systems, giving you a straightforward replacement that fits correctly and performs as expected. This 30-amp, 3-pole bolt-on breaker is commonly used in QO load centers, as well as NQ and NQOD panelboards, making it a practical option for keeping older or existing setups up and running. One thing you’ll notice right away is how easy it is to tell when the breaker has tripped. The built-in Visi-Trip indicator clearly shows when the circuit has been interrupted, which can save time when you’re tracking down an issue. It also includes a factory-installed AC shunt trip, allowing the breaker to be opened remotely—useful in situations where power needs to be shut off quickly from a distance. Internally, the breaker is designed so that if one pole detects a fault, all three poles open together. That kind of coordinated response helps protect connected equipment and keeps the system behaving the way it should. It’s a simple, reliable solution built to last and designed specifically for compatibility with existing Square D QO equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e30A, 3-pole breaker for multi-phase circuit protection\u003c\/li\u003e\n\u003cli\u003eBolt-on design for secure installation in compatible panels\u003c\/li\u003e\n\u003cli\u003eFactory-installed AC shunt trip for remote operation\u003c\/li\u003e\n\u003cli\u003eVisi-Trip indicator shows when the breaker has tripped\u003c\/li\u003e\n\u003cli\u003eAll poles open simultaneously during an overcurrent event\u003c\/li\u003e\n\u003cli\u003eQuick-make, quick-break switching mechanism\u003c\/li\u003e\n\u003cli\u003eHACR rated for HVAC-related systems\u003c\/li\u003e\n\u003cli\u003eDesigned for proper fit and function in QO equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e QOB3301021\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e QO\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 30 Amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 240V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Bolt-On\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 10kA @ 240V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShunt Trip:\u003c\/strong\u003e 120\/208\/240V AC (factory installed)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Pressure plate\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e AWG 14–8 (Copper or Aluminum)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque:\u003c\/strong\u003e 35.4 lb-in\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 3.0\" H x 3.0\" W x 2.9\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.19 lbs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient Rating:\u003c\/strong\u003e Up to 104°F (40°C)\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\u003eUL Listed (UL File E84967)\u003c\/li\u003e\n\u003cli\u003eCSA Certified\u003c\/li\u003e\n\u003cli\u003eMeets established industry safety standards\u003c\/li\u003e\n\u003cli\u003eBuilt for consistent, long-term use in rated conditions\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\u003eQO load centers using bolt-on breakers\u003c\/li\u003e\n\u003cli\u003eNQ and NQOD panelboards in commercial environments\u003c\/li\u003e\n\u003cli\u003eIndustrial distribution panels and switchboards\u003c\/li\u003e\n\u003cli\u003eOEM equipment requiring QO-compatible breakers\u003c\/li\u003e\n\u003cli\u003eEmergency shutdown systems with remote trip capability\u003c\/li\u003e\n\u003cli\u003eFire and life-safety circuits\u003c\/li\u003e\n\u003cli\u003eReplacement needs in existing electrical systems\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.
