Under normal load, the thermal component meters heat buildup and trips only when a preset overload is exceeded. If a short circuit occurs, the magnetic element provides immediate trip, isolating the fault to prevent damage and enhance safety.\u003c\/p\u003e \u003ch2\u003eTechnical snapshot\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eManufacturer: Siemens\u003c\/li\u003e \u003cli\u003ePart Number: JXD63B250\u003c\/li\u003e \u003cli\u003eType: Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003eAmperage Rating: 250A\u003c\/li\u003e \u003cli\u003eVoltage Rating: 600V\u003c\/li\u003e \u003cli\u003eNumber of Poles: 3\u003c\/li\u003e \u003cli\u003eApplications: Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eInstallation and compatibility notes\u003c\/h2\u003e\n\u003cp\u003eDesigned for seamless integration with Siemens OEM load centers and panelboards, ensuring consistent trip characteristics and electrical coordination within your panel.
