Product FAQs
7 answersWhich Siemens panelboards are compatible with the HFXD63B2501S11 circuit breaker?
This FD-frame breaker is compatible with Siemens P1, P2, P3, P4, P5, S4, S5, SPP, and FPP panelboards, as well as Siemens switchboards and motor control centers.
What does the S11 suffix mean in the HFXD63B2501S11 part number?
The S11 suffix indicates the breaker comes equipped with a factory-installed shunt trip and auxiliary switch. This allows for remote tripping and provides advanced control and monitoring capabilities for industrial panels.
What type of trip unit is installed in the HFXD63B2501S11?
It features a thermal-magnetic trip unit with fixed thermal and adjustable magnetic settings (LI: Long-Time, Instantaneous). The adjustable magnetic trip allows electricians to precisely coordinate short-circuit protection with downstream devices.
What are the wire size requirements for the lugs on this breaker?
The included load-side lugs accept wire gauges from 6 AWG up to 350 kcmil. They are rated for both copper (Cu) and aluminum (Al) conductors.
Can the HFXD63B2501S11 be used in direct current (DC) electrical systems?
Yes, in addition to AC applications, this breaker is rated for DC systems up to 500VDC, providing a 25kA interrupting capacity at that voltage.
How is the HFXD63B2501S11 installed into a panelboard?
This is a unit-mount, bolt-on circuit breaker. It bolts directly to the busbar in compatible Siemens panelboards, switchboards, and motor control centers, ensuring a secure and reliable connection.
How does the factory-installed shunt trip enhance system safety?
The shunt trip allows the HFXD63B2501S11 to be opened remotely via an external control signal. This is critical for emergency shutdowns, equipment protection, and integrating the breaker into facility safety systems.
