Siemens PXD63B160 is a three‑pole, 1,600 A, 600 V AC molded‑case circuit breaker from the Sentron PXD6 family, designed for heavy feeder protection in low‑voltage electrical distributions. It uses a thermal‑magnetic trip unit and is configured for bolt‑on installation with mounting hardware MB9301 or MBR9302, requiring six TA5P600 lugs. The model carries a 40 °C continuous current rating of 1,600 A and is UL listed for reverse‑fed configurations. For this model, Siemens specifies a 50 kA interrupting rating at 480 V, aligning with high‑fault‑current applications within appropriate systems.
