It’s a great replacement for older NB-style breakers and bolts right into place without a lot of hassle. This breaker uses a thermal magnetic trip, which means it can handle long-term load without issue but will trip fast when there’s a short or overload. It’s solid, straightforward, and built to do the job right. A lot of customers use this breaker in panel upgrades, subpanels, or when they’re replacing a breaker that’s aged out. If your setup calls for a 90A two-pole breaker with a bolt-on connection, this one fits the bill. It’s reliable, easy to work with, and designed to match the specs of the original NB frame.\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\u003eDirect Fit:\u003c\/strong\u003e Designed to replace older NB-style breakers without changes to your panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Protection:\u003c\/strong\u003e Helps prevent overheating from continuous load and reacts fast to sudden faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong Interrupting Rating:\u003c\/strong\u003e Rated at 10,000 AIC at 120\/240V to handle fault currents safely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick Install:\u003c\/strong\u003e Bolt-on design makes it easy to mount securely in the panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt to Last:\u003c\/strong\u003e Works well in demanding environments—residential, commercial, or light industrial.\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\u003eModel Number:\u003c\/strong\u003e NB90\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 90 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 120\/240V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 10kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type:\u003c\/strong\u003e Thermal Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e Bolt-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e NB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 4.25\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 2 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSafety \u0026amp; Material Standards\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Build:\u003c\/strong\u003e This breaker is made with quality components you can count on.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTested Performance:\u003c\/strong\u003e It meets key performance and safety expectations and has been tested to ensure consistent tripping and long-term durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraightforward Protection:\u003c\/strong\u003e You get reliable protection without overcomplicating things.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere This Breaker Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe NB90 is a smart choice for subpanels, HVAC units, electric water heaters, and larger appliance loads that need solid overcurrent protection.
