Product FAQs
5 answersWhich switchboards are compatible with the HPD63B160 breaker?
This breaker is specifically designed for Siemens Sentron SB1, SB2, and SB3 switchboards. It is a unit-mount, feed-thru breaker, meaning it bolts directly to the bus or mounting pan rather than utilizing a plug-in or draw-out assembly.
How does the HPD63B160 differ from a standard PD63B160?
The H prefix indicates a high-interrupting capacity frame. While standard PD breakers have lower fault current tolerances, the HPD63B160 is rated for 65kAIC at 480VAC and 100kAIC at 240VAC, making it suitable for commercial or industrial systems with higher available fault currents.
What are the standard lug wire capacity requirements for this 1600A breaker?
The factory lug configuration accepts five 300 to 600 kcmil aluminum or copper conductors per phase. Installers must ensure all five conductors are properly seated and torqued to the specifications printed on the breaker faceplate to prevent thermal failure under heavy loads.
Does the HPD63B160 offer adjustable overload protection?
No, this thermal-magnetic breaker has a fixed thermal element for long-time overload protection set at 1600 amps. However, it does feature an adjustable magnetic dial to fine-tune the instantaneous short-circuit trip threshold.
Is the HPD63B160 approved for high-capacity DC circuits?
Yes, this model carries a DC rating of 30kAIC at 250VDC and 50kAIC at 500VDC. When installing in DC applications, verify that the pole wiring configuration matches Siemens guidelines for breaking DC arcs safely.
