At 1200 A and 600 V, this 3-pole device delivers dependable overcurrent and short-circuit protection where it matters most, from large residential subpanels to light industrial distributions. Its secure bolt-on mounting creates a rigid, vibration-resistant bus connection, ensuring consistent protection even in vibration-prone settings.\u003c\/p\u003e \u003ch2\u003eWhy this breaker stands out\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSecure bolt-on mounting\u003c\/strong\u003e provides a rigid connection to the bus, reducing movement and ensuring reliable protection under vibration or load fluctuations.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThermal-magnetic trip unit\u003c\/strong\u003e delivers stable, repeatable protection by responding predictably to both overloads and sudden fault currents.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHigh-current capability\u003c\/strong\u003e at 1200 A makes it ideal for feeders and branch circuits in heavier-duty panels.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e600 V rating\u003c\/strong\u003e supports a wide range of commercial and light industrial applications while maintaining safety margins for surge and fault conditions.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOEM compatibility\u003c\/strong\u003e is engineered to pair with matching Eaton and OEM panelboards and loadcenters, simplifying installation and maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eIdeal use cases\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eResidential subpanels that feed high-demand circuits, such as electric heating or large HVAC units.\u003c\/li\u003e \u003cli\u003eCommercial panelboards supporting office complexes, retail spaces, or service equipment with elevated current requirements.\u003c\/li\u003e \u003cli\u003eLight industrial distribution where dependable protection for feeders and machinery is essential.\u003c\/li\u003e \u003cli\u003eRetrofits or replacements in OEM-installed systems that require a bolt-on, three-pole solution.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eHow it protects your system\u003c\/h2\u003e\n\u003cp\u003eThe ND312T32W is designed to intercept dangerous conditions before they impact equipment or personnel. When a circuit draws an overload current, the thermal element heats and trips to interrupt the circuit at a safe threshold. In the event of a high-magnitude fault, the magnetic element activates the trip mechanism almost instantaneously, isolating the fault and limiting damage. This combination provides both ignition-avoidance for everyday overloads and rapid fault isolation for severe short circuits.\u003c\/p\u003e \u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Eaton\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e ND312T32W\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage rating:\u003c\/strong\u003e 1200 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 600 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNumber of poles:\u003c\/strong\u003e 3\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMounting style:\u003c\/strong\u003e Bolt-on\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eDesigned for reliability in panelboards and loadcenters, the Eaton ND312T32W (1192000-series style) delivers a precise balance of high current capability, secure installation, and OEM compatibility.
