If a sustained overload occurs, the thermal element slowly responds to heat buildup. In the event of a sudden fault current, the magnetic element trips quickly to interrupt the circuit, preventing damage to conductors, devices, and downstream equipment. This dual-action protection is particularly valuable in panels that feed motors, compressors, or power distribution blocks in busy, multi-circuit environments.\u003c\/p\u003e \u003ch3\u003eTechnical snapshot\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 FAZ-D40\/3N\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 40A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 480V\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 \u003ch3\u003eIdeal use scenarios\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eProtection for 3-phase feeders supplying motors, HVAC equipment, or transformers in commercial and light industrial environments\u003c\/li\u003e \u003cli\u003eReplacement in existing Eaton OEM panelboards and loadcenters to maintain consistent protection class and trip characteristics\u003c\/li\u003e \u003cli\u003eSpace-conscious panel upgrades where maintaining 480V 3-phase protection is required without expanding enclosure size\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWith the Eaton FAZ-D40\/3N, you get dependable, industry-grade protection tailored to 480V three-phase systems, backed by a compact footprint and seamless compatibility with Eaton panel products.
