A drop-in replacement for older commercial and industrial systems, the Federal Pacific HF631015R restores functionality to existing infrastructure. This 15A, 3-pole molded case circuit breaker is specifically designed to mount into legacy FPE F-Frame panelboards without requiring panel modifications. Rated for 22 kAIC at 480VAC and up to 600VAC maximum, it provides reliable thermal-magnetic protection for aging electrical distribution networks.
Which panelboards are compatible with the Federal Pacific HF631015 circuit breaker?
This breaker is designed as a direct replacement for legacy Federal Pacific F-Frame panelboards. It maintains the exact dimensions of the original hardware, allowing it to mount securely without requiring aftermarket retrofit kits.
Does this breaker belong to the F-Frame or H-Frame family?
While it is designed to be installed in Federal Pacific F-Frame panelboards, the HF631015 itself is classified under the H-Frame group of legacy molded case circuit breakers.
What wire sizes are accepted by the load side terminals on this breaker?
The included load side lug terminals accommodate conductors ranging from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Can the HF631015 be used on 480V systems with high fault current availability?
It is rated for up to 22 kAIC at 480VAC, and 25 kAIC at 240VAC. Before installation, verify that the available fault current at the panelboard does not exceed these ratings to ensure proper overcurrent protection.
Is this breaker suitable for 600V industrial applications?
Yes, the HF631015 has a maximum voltage rating of 600VAC. When applied at 600V, it provides an interrupting capacity of 14 kAIC.
Are the trip settings on the HF631015 adjustable?
No, this breaker features fixed thermal and fixed magnetic trip elements. It provides standard long-time and instantaneous (LI) protection without the ability to adjust the trip curve in the field.
What type of overcurrent protection does the HF631015 provide?
It utilizes thermal-magnetic trip technology to protect against two types of faults. The thermal element responds to prolonged overloads, while the magnetic element trips immediately in the event of a severe short circuit.
Is the Federal Pacific HF631015 still actively manufactured?
Federal Pacific Electric (FPE) is a legacy brand, and original production of the HF series has ceased. However, exact replacements are still available to maintain and service existing F-Frame panelboards without requiring a complete system upgrade.
