Siemens HPD63F160 U 1600A 3P 600V 35K Molded Case Circuit Breaker

Siemens HPD63F160 U is a 3-pole molded‑case circuit breaker built on the HPD63 frame, rated for 1600 A at 600 V, with a thermal‑magnetic trip unit for overload and short‑circuit protection. It provides a rated interrupting capacity of 25 kAIC at 600 V and 50 kAIC at 480 V, making it suitable for demanding industrial feeders and distribution panels in 3‑phase 600 V systems. The frame is sold as a frame‑only component (HPD63F160) or as a complete unassembled breaker (HPD63B160), and requires mounting hardware MB9301 or MBR9302 and six lugs TA5P600 for installation. This configuration is commonly applied in heavy‑duty power distribution, switchgear, panelboards, and bus duct setups where high current protection is needed.
