Built for commercial applications, the HF631015 delivers robust overcurrent protection. This 15A, 3-pole MCCB maintains the exact dimensions of original Federal Pacific hardware. It installs securely into legacy F-Frame panelboards via a standard bolt-on connection, eliminating the need for retrofit kits. It also crosses to the UBIF015 substitute. Providing 22 kAIC at 480VAC, the unit utilizes fixed thermal-magnetic trip elements to handle long-time and instantaneous faults.
Which legacy panelboards are compatible with the HF631015?
This molded case circuit breaker is engineered as a direct replacement for older Federal Pacific F-Frame panelboards, restoring functionality to existing commercial and industrial infrastructure.
Does installing the HF631015 require retrofit kits for older panels?
No. It maintains the exact dimensions of the original Federal Pacific hardware and uses a standard bolt-on connection, allowing it to mount securely without any panel modifications.
What wire gauge range is supported by the load side lugs?
The included terminal lugs accommodate a wide range of conductors, accepting wire sizes from 14 AWG up to 1/0 AWG to support various field wiring requirements.
How does the interrupting capacity scale across different system voltages?
The breaker delivers a maximum short circuit rating of 25kA at 240VAC, which scales to 22kA at 480VAC and 14kA at 600VAC for higher voltage industrial applications.
Are the thermal and magnetic trip elements adjustable on this model?
No, the HF631015 utilizes fixed thermal and fixed magnetic trip elements to provide reliable long-time and instantaneous (LI) overcurrent protection.
Can this breaker replace older H-Frame Federal Pacific units?
Yes, it belongs to the legacy H-Frame group and serves as an exact replacement for aging 15A, 3-pole MCCBs in Federal Pacific distribution systems.
Is the HF631015 suitable for high-voltage industrial applications?
Yes, with a maximum voltage rating of 600VAC and robust thermal-magnetic protection, it is designed to safely interrupt faults in heavy commercial and industrial electrical networks.
