Description
Engineered to support three-phase electrical systems, this 80-amp molded case circuit breaker provides essential thermal-magnetic protection for commercial facilities operating up to 600VAC. The bolt-on device installs into legacy Federal Pacific enclosures, seamlessly replacing discontinued NEG631080 and NEF631080 models. This ensures a safe, code-compliant fit for older infrastructure. With a 22 kAIC rating at 480V, the breaker reliably clears overloads and short circuits.Specifications

Product FAQs
7 answersWhat panels accept the HEG631080 circuit breaker?
This 3-pole breaker is designed specifically for legacy Federal Pacific commercial and industrial panelboards configured for H-Frame, bolt-on breakers.
Can the HEG631080 replace older NEF or NEG series breakers?
Yes, the HEG series shares the same physical footprint and bolt-on mounting configuration as the older NEF and NEG series. The HEG631080 serves as a direct drop-in replacement for the NEF631080 or NEG631080, offering a higher interrupting capacity without requiring panel modifications.
Is the Federal Pacific HEG631080 still in production?
No, Federal Pacific Electric (FPE) is no longer in business. The HEG631080 is a legacy component used to maintain existing electrical infrastructure without the need for a complete panel retrofit.
What wire sizes are compatible with the load lugs on this breaker?
The factory-installed load side lugs accept wire gauges from 14 AWG up to 1/0 AWG. Ensure you use the appropriate wire size and torque specifications for an 80-amp circuit as required by the National Electrical Code (NEC).
Does this breaker require a special mounting kit?
No, the HEG631080 is a standard bolt-on breaker that mounts directly to the bus bars of compatible Federal Pacific panelboards. No additional retrofit kits are required for installation.
What type of protection does the HEG631080 provide?
It uses a fixed thermal-magnetic trip unit with long-time (L) and instantaneous (I) functions. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short-circuit events.
What should be inspected before installing a replacement FPE breaker?
Before bolting in the HEG631080, a licensed electrician should inspect the panelboard's bus bars for any signs of pitting, corrosion, or heat damage to ensure a secure and safe electrical connection.
