Siemens JD63B350 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 350A current rating and a 600V voltage rating, housed within a robust JD frame with a bolt-on connection for secure installation. The breaker utilizes a thermal-magnetic trip unit offering both long-time and instantaneous (LI) protection functions and is constructed to operate reliably across a temperature range of -25°C to 70°C. It complies with key industry standards, including UL and IEC certifications, and meets RoHS requirements, ensuring safety and environmental compliance. This breaker is typically applied in panelboards, switchboards, and industrial control panels where a 35kA interrupting capacity at 480V is required for system protection.
