Description
Built for heavy-duty commercial use, the Siemens HHFD63B100 is a 100A, 3-pole molded case circuit breaker from the proven Sentron family. Designed for unit mounting, it fits standard Siemens enclosures and panelboards. The modern replacement is the 3VA5210-7EC31-0AA0, which requires a panel retrofit kit. This FD frame breaker boasts an extra high 100kAIC rating at 480V. It utilizes a thermal-magnetic trip mechanism with long-time and instantaneous (LI) functions.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the HHFD63B100 breaker?
This unit-mount FD frame breaker is designed for installation in Siemens Sentron series panelboards, switchboards, and standalone enclosures. It requires a bolt-on connection and appropriate mounting hardware for the specific enclosure type.
What are the acceptable wire sizes for the standard lugs on this breaker?
The included lugs accept 6 AWG to 350 kcmil copper (Cu) conductors or 4 AWG to 350 kcmil aluminum (Al) conductors. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
How does the HHFD frame differ from standard FD or HFD frames?
The HH designation indicates an ultra-high interrupting capacity. While standard FD frames offer 35kAIC at 480VAC and HFD frames offer 65kAIC at 480VAC, the HHFD frame provides up to 100kAIC at 480VAC for systems with higher available fault currents.
How is the instantaneous trip function adjusted on the HHFD63B100?
The breaker features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic trip threshold is configured using the adjustment dial located on the front of the breaker.
Can the HHFD63B100 replace an older FD63B100 or HFD63B100?
Yes, it shares the same physical dimensions and bolt-on mounting footprint as standard FD6 and HFD6 breakers. It can be used as a direct replacement or upgrade when a higher short-circuit interrupting rating is required by the system study.
What is the primary use case for the adjustable magnetic trip on this 100A breaker?
The adjustable instantaneous trip allows electricians to fine-tune the short-circuit response to prevent nuisance tripping. This is particularly useful in applications with high inrush currents, such as motor circuits or large transformer loads.
