Product FAQs
5 answersWhat enclosures and panelboards are compatible with the HFD63B250 breaker?
This bolt-on breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers that accommodate FD frame molded case circuit breakers.
Is the thermal magnetic trip unit on the HFD63B250 adjustable?
The thermal long-time trip is fixed at 250 amps. However, the instantaneous magnetic trip setting is adjustable, allowing you to fine-tune short circuit protection for coordination with downstream loads.
What wire gauge is supported by the standard lugs on this 250A breaker?
The included lugs accept copper wire from 6 AWG to 350 kcmil, and aluminum conductors from 4 AWG to 350 kcmil. Ensure all connections are torqued to manufacturer specifications during installation.
How does the HFD63B250 differ from standard FD6 series breakers?
The H prefix designates a high interrupting capacity. Standard FD6 breakers typically offer 35kAIC at 480VAC, whereas the HFD63B250 provides 65kAIC at 480VAC for environments with higher available fault currents.
Can the HFD63B250 be utilized in direct current systems?
Yes, this thermal magnetic breaker carries a DC rating. It provides up to 25kAIC at 500VDC, making it suitable for industrial DC control panels and compatible distribution equipment.
