Product FAQs
6 answersWhich panelboards are compatible with the HF631040?
This breaker is engineered specifically for Federal Pacific F-Frame panelboards. It allows facilities to replace aging or failed components directly without upgrading the entire panel enclosure.
What protection functions does the HF631040 provide?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) protection. The thermal mechanism protects against sustained overcurrents, while the magnetic mechanism provides immediate tripping during short circuits.
Is the Federal Pacific HF series still being manufactured?
No, Federal Pacific Electric (FPE) circuit breakers are obsolete. The HF631040 is utilized as a direct replacement component to service and maintain existing legacy FPE electrical systems.
What type of terminations are provided on the HF631040?
This breaker includes load-side lug terminals designed to accept 14 AWG to 1/0 AWG conductors. Installers must ensure proper torque is applied to the lugs to maintain a secure connection and prevent overheating under load.
How is the HF631040 secured within the panelboard?
It utilizes a bolt-on mounting style that fastens directly to the panelboard bus. This provides a rigid, high-conductivity connection for industrial applications without the need for aftermarket mounting kits.
What safety procedures apply when installing this replacement breaker?
Installation must be performed by a qualified electrician. The panelboard must be completely de-energized before unbolting the old unit, and the replacement must be verified to match the system's voltage and fault current requirements.
