Siemens JXD63B350H 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 600V AC voltage rating and a 350A continuous current rating, housed within a compact JD frame with bolt-on connections and dimensions of 8.661" x 12.992" x 6.707" (220mm x 330mm x 170.4mm). The breaker is certified to UL and IEC standards, complies with RoHS, and operates effectively across a wide temperature range from -25°C to 70°C. Its thermal-magnetic protection with long-time and instantaneous trip functions and a 35kA interrupting capacity at 480V AC makes it suitable for protecting feeders, motors, and other critical loads in commercial and industrial panelboards.
