Product FAQs
5 answersWhich older Federal Pacific breakers can the HEG631020 replace?
The HEG631020 serves as a direct drop-in replacement for legacy NEG631020 and NEF631020 circuit breakers. Using this breaker allows you to restore overcurrent protection without requiring panel upgrades or retrofit kits.
What type of panelboards accept the HEG631020 circuit breaker?
This H-frame breaker is designed specifically for installation in legacy Federal Pacific (FPE) commercial and industrial panelboards that utilize bolt-on connections.
How is the HEG631020 secured to the panel busbar?
It utilizes a bolt-on mounting style. This provides a highly secure, vibration-resistant connection suitable for demanding industrial environments where plug-on breakers might not be permitted.
What wire sizes do the terminals on the HEG631020 accept?
The factory-installed lugs are rated to accept conductors ranging from 14 AWG to 1/0 AWG, providing ample flexibility for sizing wire to account for voltage drop in 20A circuits.
What type of overcurrent protection does the HEG631020 provide?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short-circuit faults.
