In practical terms, it protects conductors and equipment from overcurrent conditions and short circuits by tripping when the current exceeds safe limits. The 3-pole configuration provides coordinated protection across three-phase systems common in commercial and industrial panels, while the bolt-on mounting ensures a solid, bus-friendly installation in appropriately rated enclosures.\u003c\/p\u003e \u003cp\u003eUse cases include feeding large branch circuits in panelboards, main feeders in commercial loadcenters, and as a reliable protection device in light industrial control panels. When replacing an older unit, verify that the mounting style and trip characteristics match the OEM panel requirements to ensure seamless integration.\u003c\/p\u003e \u003ch2\u003eTechnical snapshot\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e General Electrics\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e THKMA836500\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 500A\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 \u003ch2\u003ePractical tips for installation and maintenance\u003c\/h2\u003e \u003cp\u003eEnsure the enclosure accepts a bolt-on MCCB of this rating and pole count.
