Product FAQs
6 answersWhat panelboards are compatible with the HEJ233175 circuit breaker?
This breaker is designed exclusively for legacy Federal Pacific panelboards configured to accept H-frame or HEJ-series bolt-on breakers.
What wire gauge range is supported by the lugs on this breaker?
The terminal lugs accept conductor sizes ranging from 4 AWG up to 300 kcmil. Ensure you use the correct torque specifications during installation to prevent terminal overheating.
What does the LI trip function code mean on the HEJ233175?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (thermal) overload protection and Instantaneous (magnetic) short-circuit protection. Both functions are fixed and non-adjustable on this model.
Are Federal Pacific HEJ breakers still in active production?
No. Federal Pacific Electric (FPE) is no longer in business. The HEJ233175 is a legacy component used primarily by facility managers and electricians to maintain and service existing FPE infrastructure without replacing the entire panel.
How is the HEJ233175 secured inside the electrical panel?
It utilizes a bolt-on connection type. The breaker must be mechanically bolted directly to the panelboard busbars, providing a secure, vibration-resistant connection compared to standard plug-on designs.
Is it safe to replace a single Federal Pacific breaker in an older panel?
Replacing a faulty breaker with an exact match like the HEJ233175 can restore functionality to a legacy panel. However, because FPE equipment is obsolete, a licensed electrician should thoroughly inspect the panel busbars and overall system condition before installation.
