The thermal-magnetic trip unit reacts to both heating (overload) and magnetic (short-circuit) conditions, delivering fast, predictable tripping that you can count on in demanding environments. By interrupting all three poles in a 3-phase circuit, it prevents dangerous arc scenarios and keeps equipment and personnel safer.\u003c\/p\u003e \u003ch3\u003eCompatibility, installation, and reliability\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e designed to pair with Eaton panelboards and loadcenters, ensuring a cohesive, one-brand protection strategy across your electrical system.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e straightforward integration with standard panel enclosures; ideal for field replacements or new installations where compact protection is required.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e built to withstand routine commercial and light industrial duty, delivering consistent protection over time.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eTechnical specifications at a glance\u003c\/h3\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 FD3045L\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 45 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\u003eApplication:\u003c\/strong\u003e Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eUpgrade or install the Eaton FD3045L to deliver precise, reliable protection for your panelboards and loadcenters.
