Product FAQs
5 answersWhat equipment is the HHLD63B400 designed to be installed in?
This LD frame breaker is compatible with Siemens Sentron panelboards, switchboards, motor control centers, and standalone enclosures.
What is the wire capacity for the standard lugs on this breaker?
The factory lugs accept two conductors per phase. They are rated for 3/0 AWG to 500 kcmil copper wire, or 4/0 AWG to 500 kcmil aluminum wire.
Can the trip settings on the HHLD63B400 be adjusted?
Yes, while the thermal overload protection is fixed at 400 amps, the magnetic instantaneous trip is adjustable to allow for coordination with other devices in your electrical system.
What does the HHLD frame designation mean compared to standard LD frames?
The HH prefix indicates an extra-high interrupting capacity tier within the Siemens Sentron LD frame family. It provides a higher fault current rating, such as 100kAIC at 480V, compared to standard LD or HLD breakers.
Does this breaker require a special mounting kit?
The HHLD63B400 is a unit-mount, bolt-on breaker. It bolts directly to the bus in compatible Siemens distribution equipment without requiring a separate plug-in mounting base.
