Product FAQs
5 answers
What equipment is compatible with the HFD63B200 breaker?
This bolt-on device is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers that accept FD frame molded case circuit breakers.
What does the H signify in the HFD63B200 catalog number?
It denotes the high interrupting capacity version of the Siemens Sentron FD frame. This model provides a 65kAIC rating at 480VAC, offering higher fault current protection than standard interrupting models.
Are the factory lugs rated for aluminum wiring?
Yes, the included lugs accept both copper and aluminum conductors. The acceptable wire size range is 6 AWG to 350 kcmil for copper and 4 AWG to 350 kcmil for aluminum.
What is the benefit of the adjustable magnetic trip on this Sentron breaker?
While the thermal overload protection is fixed at 200 amps, the adjustable magnetic element allows panel builders to set the instantaneous short circuit trip threshold. This helps coordinate with downstream protection devices and prevents nuisance tripping from equipment inrush currents.
Can the HFD63B200 be installed in DC electrical systems?
Yes, it is rated for use in direct current systems up to 500VDC, where it provides a maximum interrupting capacity of 25kAIC.
