Siemens JXD23B400 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 400A current rating and a 240V AC voltage rating, housed within a compact 400A/JD frame with dimensions of 8.661" x 12.992" x 6.704" (220 x 330 x 170.3 mm) and a weight of 18.301 lb. The breaker is constructed for bolt-on connection with lug terminals, compliant with RoHS standards, and carries UL and IEC certifications for safety. Its thermal-magnetic protection with long-time and instantaneous trip functions, combined with a 65kA interrupting rating at 240V, makes it suitable for installation in SB switchboards and Sentron panelboards, operating reliably in ambient temperatures from -25°C to 70°C.
