Product FAQs
7 answersWhich panelboards accept the Federal Pacific HF631070?
This breaker is specifically designed to restore functionality to legacy Federal Pacific F-Frame panelboards. It is fully compatible with existing F-Frame hardware.
What is the recommended cross-reference for the discontinued HF631070?
The UBIF070 is a verified, drop-in substitute that matches the physical dimensions and electrical specifications of this legacy Federal Pacific breaker.
What type of connections are required for installing the HF631070?
Installation requires bolting the breaker directly to the panelboard bus. The load side features mechanical lugs that accommodate 14 to 1/0 AWG wiring.
How does the interrupting capacity scale with different system voltages?
The fault-clearing capacity decreases as system voltage increases. It provides 25kAIC at 240VAC, 22kAIC at 480VAC, and 14kAIC at 600VAC for commercial and industrial applications.
Can the trip curve be adjusted for specific load requirements?
No. This breaker utilizes fixed thermal and fixed magnetic trip elements, meaning the Long-Time and Instantaneous protection thresholds cannot be modified in the field.
What type of fault protection does the thermal-magnetic mechanism provide?
The thermal element provides Long-Time protection against sustained overloads, while the magnetic element delivers Instantaneous protection to safely clear short circuits.
What is the difference between the 250A frame and 70A trip rating on this breaker?
The 250A frame size dictates the physical dimensions and maximum current capacity the breaker housing can handle, while the 70A trip rating is the specific current limit at which this unit will open the circuit.
